text: Receptor tyrosine kinases (RTKs) are a large family of cell surface receptors
that sense growth factors and hormones and regulate a variety of cell behaviours
in health and disease. Contactless activation of RTKs with spatial and temporal
precision is currently not feasible. Here, we generated RTKs that are insensitive
to endogenous ligands but can be selectively activated by low-intensity blue light.
We screened light-oxygen-voltage (LOV)-sensing domains for their ability to activate
RTKs by light-activated dimerization. Incorporation of LOV domains found in aureochrome
photoreceptors of stramenopiles resulted in robust activation of the fibroblast
growth factor receptor 1 (FGFR1), epidermal growth factor receptor (EGFR) and
rearranged during transfection (RET). In human cancer and endothelial cells, light
induced cellular signalling with spatial and temporal precision. Furthermore,
light faithfully mimicked complex mitogenic and morphogenic cell behaviour induced
by growth factors. RTKs under optical control (Opto-RTKs) provide a powerful optogenetic
approach to actuate cellular signals and manipulate cell behaviour.

text: The impact of disulfide bonds on protein stability goes beyond simple equilibrium
thermodynamics effects associated with the conformational entropy of the unfolded
state. 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.

text: In the vibrant field of optogenetics, optics and genetic targeting are combined
to commandeer cellular functions, such as the neuronal action potential, by optically
stimulating light-sensitive ion channels expressed in the cell membrane. One broadly
applicable manifestation of this approach are covalently attached photochromic
tethered ligands (PTLs) that allow activating ligand-gated ion channels with outstanding
spatial and temporal resolution. Here, we describe all steps towards the successful
development and application of PTL-gated ion channels in cell lines and primary
cells. The basis for these experiments forms a combination of molecular modeling,
genetic engineering, cell culture, and electrophysiology. The light-gated glutamate
receptor (LiGluR), which consists of the PTL-functionalized GluK2 receptor, serves
as a model.

text: 'G protein–coupled receptors (GPCRs), the largest family of membrane signaling
proteins, respond to neurotransmitters, hormones and small environmental molecules.
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.'

text: Alkyd resins are polyesters containing unsaturated fatty acids that are used
as binding agents in paints and coatings. 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.

text: Under physiological conditions the brain, via the purine salvage pathway,
reuses the preformed purine bases hypoxanthine, derived from ATP degradation,
and adenine (Ade), derived from polyamine synthesis, to restore its ATP pool.
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.

text: Glutamate is the major excitatory neurotransmitter in the mammalian central
nervous system and gates non-selective cation channels. The origins of glutamate
receptors are not well understood as they differ structurally and functionally
from simple bacterial ligand-gated ion channels. Here we report the discovery
of an ionotropic glutamate receptor that combines the typical eukaryotic domain
architecture with the 'TXVGYG' signature sequence of the selectivity filter found
in K+ channels. This receptor exhibits functional properties intermediate between
bacterial and eukaryotic glutamate-gated ion channels, suggesting a link in the
evolution of ionotropic glutamate receptors.
