Construction of genetically encoded biosensors generally relies on the availability of a binding "core" that is both specific and stable, which can then be combined with fluorescent molecules to create a sensor. However, binding proteins with the desired properties are often not available in nature and substantial improvement to sensors can be required, particularly with regard to their durability. Ancestral protein reconstruction is a powerful protein-engineering tool able to generate highly stable and functional proteins. In this work, we sought to establish the utility of ancestral protein reconstruction to biosensor development, beginning with the construction of an l-arginine biosensor. l-arginine, as the immediate precursor to nitric oxide, is an important molecule in many physiological contexts including brain function. Using a combination of ancestral reconstruction and circular permutation, we constructed a Förster resonance energy transfer (FRET) biosensor for l-arginine (cpFLIPR). cpFLIPR displays high sensitivity and specificity, with a Kd of ∼14 μM and a maximal dynamic range of 35%. Importantly, cpFLIPR was highly robust, enabling accurate l-arginine measurement at physiological temperatures. We established that cpFLIPR is compatible with two-photon excitation fluorescence microscopy and report l-arginine concentrations in brain tissue."}],"issue":"9","type":"journal_article","oa_version":"Submitted Version","title":"Construction of a robust and sensitive arginine biosensor through ancestral protein reconstruction","status":"public","intvolume":" 24","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"1611","day":"01","scopus_import":1,"date_published":"2015-09-01T00:00:00Z","page":"1412 - 1422","publication":"Protein Science","citation":{"mla":"Whitfield, Jason, et al. “Construction of a Robust and Sensitive Arginine Biosensor through Ancestral Protein Reconstruction.” Protein Science, vol. 24, no. 9, Wiley, 2015, pp. 1412–22, doi:10.1002/pro.2721.","short":"J.

Flavin cofactors, in particular flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD), are critical for cellular redox reactions and sense light in naturally occurring photoreceptors and optogenetic tools. Here, we quantified flavin contents of commonly used mammalian cell lines. We first compared three procedures for extraction of free and noncovalently protein-bound flavins and verified extraction using fluorescence spectroscopy. For separation, two CE methods with different BGEs were established, and detection was performed by LED-induced fluorescence with limit of detections (LODs 0.5-3.8 nM). We found that riboflavin (RF), FMN, and FAD contents varied significantly between cell lines. RF (3.1-14 amol/cell) and FAD (2.2-17.0 amol/cell) were the predominant flavins, while FMN (0.46-3.4 amol/cell) was found at markedly lower levels. Observed flavin contents agree with those previously extracted from mammalian tissues, yet reduced forms of RF were detected that were not described previously. Quantification of flavins in mammalian cell lines will allow a better understanding of cellular redox reactions and optogenetic tools.","lang":"eng"}],"intvolume":" 36","title":"Quantification of riboflavin, flavin mononucleotide, and flavin adenine dinucleotide in mammalian model cells by CE with LED-induced fluorescence detection","status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"1867","oa_version":"None","pubrep_id":"836","scopus_import":1,"day":"01","page":"518 - 525","citation":{"short":"J.

It has been recently debated whether these preferences remain approximately constant during evolution or whether, due to coevolution of sites, they change strongly. Such research highlights an unresolved and fundamental issue with far-reaching implications for phylogenetic analysis and molecular evolution modeling. Here, we take advantage of the recent availability of phenotypically supported laboratory resurrections of Precambrian thioredoxins and β-lactamases to experimentally address the change of site-specific amino acid preferences over long geological timescales. Extensive mutational analyses support the notion that evolutionary adjustment to a new amino acid may occur, but to a large extent this is insufficient to erase the primitive preference for amino acid replacements. Generally, site-specific amino acid preferences appear to remain conserved throughout evolutionary history despite local sequence divergence. We show such preference conservation to be readily understandable in molecular terms and we provide crystallographic evidence for an intriguing structural-switch mechanism: Energetic preference for an ancestral amino acid in a modern protein can be linked to reorganization upon mutation to the ancestral local structure around the mutated site. Finally, we point out that site-specific preference conservation naturally leads to one plausible evolutionary explanation for the existence of intragenic global suppressor mutations."}],"issue":"2"},{"author":[{"full_name":"Inglés Prieto, Álvaro","id":"2A9DB292-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-5409-8571","first_name":"Álvaro","last_name":"Inglés Prieto"},{"last_name":"Gschaider-Reichhart","first_name":"Eva","orcid":"0000-0002-7218-7738","id":"3FEE232A-F248-11E8-B48F-1D18A9856A87","full_name":"Gschaider-Reichhart, Eva"},{"full_name":"Schelch, Karin","last_name":"Schelch","first_name":"Karin"},{"orcid":"0000-0002-8023-9315","id":"33BA6C30-F248-11E8-B48F-1D18A9856A87","last_name":"Janovjak","first_name":"Harald L","full_name":"Janovjak, Harald L"},{"first_name":"Michael","last_name":"Grusch","full_name":"Grusch, Michael"}],"date_updated":"2021-01-12T06:54:51Z","date_created":"2018-12-11T11:55:19Z","volume":1,"year":"2014","publication_status":"published","department":[{"_id":"HaJa"}],"publisher":"Taylor & Francis","file_date_updated":"2020-07-14T12:45:26Z","publist_id":"5040","article_number":"e964045","doi":"10.4161/23723548.2014.964045","language":[{"iso":"eng"}],"tmp":{"name":"Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc/4.0/legalcode","image":"/images/cc_by_nc.png","short":"CC BY-NC (4.0)"},"oa":1,"quality_controlled":"1","month":"12","file":[{"file_name":"2014_Taylor_Alvaro.pdf","access_level":"open_access","file_size":1765933,"content_type":"application/pdf","creator":"kschuh","relation":"main_file","file_id":"6464","date_created":"2019-05-16T13:39:11Z","date_updated":"2020-07-14T12:45:26Z","checksum":"44e17ad40577ab46eb602e88a8b0b8fd"}],"oa_version":"Published Version","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","_id":"2032","status":"public","ddc":["570"],"title":"The optogenetic promise for oncology: Episode I","intvolume":" 1","abstract":[{"lang":"eng","text":"As light-based control of fundamental signaling pathways is becoming a reality, the field of optogenetics is rapidly moving beyond neuroscience.

Indeed, disulfide crosslinks may play a role in the prevention of dysfunctional association and strongly affect the rates of irreversible enzyme inactivation, highly relevant in biotechnological applications. While these kinetic-stability effects remain poorly understood, by analogy with proposed mechanisms for processes of protein aggregation and fibrillogenesis, we propose that they may be determined by the properties of sparsely-populated, partially-unfolded intermediates. Here we report the successful design, on the basis of high temperature molecular-dynamics simulations, of six thermodynamically and kinetically stabilized variants of phytase from Citrobacter braakii (a biotechnologically important enzyme) with one, two or three engineered disulfides. Activity measurements and 3D crystal structure determination demonstrate that the engineered crosslinks do not cause dramatic alterations in the native structure. The inactivation kinetics for all the variants displays a strongly non-Arrhenius temperature dependence, with the time-scale for the irreversible denaturation process reaching a minimum at a given temperature within the range of the denaturation transition. We show this striking feature to be a signature of a key role played by a partially unfolded, intermediate state/ensemble. Energetic and mutational analyses confirm that the intermediate is highly unfolded (akin to a proposed critical intermediate in the misfolding of the prion protein), a result that explains the observed kinetic stabilization. Our results provide a rationale for the kinetic-stability consequences of disulfide-crosslink engineering and an experimental methodology to arrive at energetic/structural descriptions of the sparsely populated and elusive intermediates that play key roles in irreversible protein denaturation."}],"issue":"7","publication":"PLoS One","citation":{"apa":"Sanchez-Romero, I., Ariza, A., Wilson, K., Skjøt, M., Vind, J., De Maria, L., … Sánchez Ruiz, J.

The neuronal function of many GPCRs has been difficult to resolve because of an inability to gate them with subtype specificity, spatial precision, speed and reversibility. To address this, we developed an approach for opto-chemical engineering of native GPCRs. We applied this to the metabotropic glutamate receptors (mGluRs) to generate light-agonized and light-antagonized mGluRs (LimGluRs). The light-agonized LimGluR2, on which we focused, was fast, bistable and supported multiple rounds of on/off switching. Light gated two of the primary neuronal functions of mGluR2: suppression of excitability and inhibition of neurotransmitter release. We found that the light-antagonized tool LimGluR2-block was able to manipulate negative feedback of synaptically released glutamate on transmitter release. We generalized the optical control to two additional family members: mGluR3 and mGluR6. This system worked in rodent brain slices and in zebrafish in vivo, where we found that mGluR2 modulated the threshold for escape behavior. These light-gated mGluRs pave the way for determining the roles of mGluRs in synaptic plasticity, memory and disease."}],"citation":{"ista":"Levitz J, Pantoja C, Gaub B, Janovjak HL, Reiner A, Hoagland A, Schoppik D, Kane B, Stawski P, Schier A, Trauner D, Isacoff E. 2013.

Chemical drying of these polyesters is based on heavy metal catalyzed cross-linking of the unsaturated fatty acid moieties. Among the heavy-metal catalysts, cobalt complexes are the most effective, yet they have been proven to be carcinogenic. Therefore, strategies to replace the cobalt-based catalyst by environmentally friendlier and less toxic alternatives are under development. Here, we demonstrate for the first time that a laccase-mediator system can effectively replace the heavy-metal catalyst and cross-link alkyd resins. Interestingly, the biocatalytic reaction does not only work in aqueous media, but also in a solid film, where enzyme diffusion is limited. Within the catalytic cycle, the mediator oxidizes the alkyd resin and is regenerated by the laccase, which is uniformly distributed within the drying film as evidenced by confocal laser scanning microscopy. During gradual build-up of molecular weight, there is a concomitant decrease of the oxygen content in the film. A new optical sensor to follow oxygen consumption during the cross-linking reaction was developed and validated with state of the art techniques. A remarkable feature is the low sample amount required, which allows faster screening of new catalysts.","lang":"eng"}],"publist_id":"7313","issue":"2"},{"publication_identifier":{"isbn":["9781461439028"],"eisbn":["9781461439035"]},"article_processing_charge":"No","month":"07","day":"23","scopus_import":"1","language":[{"iso":"eng"}],"doi":"10.1007/978-1-4614-3903-5_6","date_published":"2012-07-23T00:00:00Z","page":"109-129","quality_controlled":"1","citation":{"ista":"zur Nedden S, Doney AS, Frenguelli BG. 2012.The double-edged sword: Gaining Adenosine at the expense of ATP.

However, the massive degradation of ATP during ischemia, although providing valuable neuroprotective adenosine, results in the accumulation and loss of diffusible purine metabolites and thereby leads to a protracted reduction in the post-ischemic ATP pool size. In vivo, this may both limit the ability to deploy ATP-dependent reparative mechanisms and reduce the subsequent availability of adenosine, whilst in brain slices results in tissue with substantially lower levels of ATP than in vivo. In the present review, we describe the mechanisms by which brain tissue replenishes its ATP, how this can be improved with the clinically tolerated chemicals D-ribose and adenine, and the functional, and potential therapeutic, implications of doing so."}],"place":"New York","type":"book_chapter","oa_version":"None","date_updated":"2022-06-21T11:51:58Z","date_created":"2022-03-21T07:16:12Z","edition":"1","author":[{"id":"3C77F464-F248-11E8-B48F-1D18A9856A87","last_name":"zur Nedden","first_name":"Stephanie","full_name":"zur Nedden, Stephanie"},{"last_name":"Doney","first_name":"Alexander S.","full_name":"Doney, Alexander S."},{"last_name":"Frenguelli","first_name":"Bruno G.","full_name":"Frenguelli, Bruno G."}],"department":[{"_id":"HaJa"}],"editor":[{"last_name":"Masino","first_name":"Susan","full_name":"Masino, Susan"},{"full_name":"Boison, Detlev","last_name":"Boison","first_name":"Detlev"}],"publisher":"Springer","title":"The double-edged sword: Gaining Adenosine at the expense of ATP.
