The kynurenine pathway and the brain: challenges, controversies and promises [PDF]

open access: yes, 2017
Research on the neurobiology of the kynurenine pathway has suffered years of relative obscurity because tryptophan degradation, and its involvement in both physiology and major brain diseases, was viewed almost exclusively through the lens of the well ...

An Update: Enzymatic Synthesis for Industrial Applications

open access: yesAngewandte Chemie International Edition, EarlyView.
Biocatalysis has become a sustainable and cost‐competitive alternative to established chemical synthesis, enabling the enzyme‐based production of not only commodity chemicals but (non‐natural) amino acids, (rare) sugars, as well as synthetic nucleotides.

Tris+/Na+ permeability ratios of nicotinic acetylcholine receptors are reduced by mutations near the intracellular end of the M2 region [PDF]

open access: yes, 1992
Tris+/Na+ permeability ratios were measured from shifts in the biionic reversal potentials of the macroscopic ACh-induced currents for 3 wild- type (WT), 1 hybrid, 2 subunit-deficient, and 25 mutant nicotinic receptors expressed in Xenopus oocytes.

Deciphering the skeletal interoceptive circuitry to control bone homeostasis

open access: yesBMEMat, EarlyView.
This review introduces the skeletal interoceptive circuitry, covering the ascending signals from bone tissues to the brain (sensors), the central neural circuits that integrate this information and dispatch commands (CPU), and the descending pathways that regulate bone homeostasis (effectors).

Selection of a biocontrol agent based on a potential mechanism of action: degradation of nicotinic acid, a growth factor essential for Erwinia amylovora [PDF]

open access: yes, 2011
This work describes a medium-based screening method for selecting microbial biocontrol agents against Erwinia amylovora based on the degradation of a specific growth factor.

The MX-Helix of Muscle nAChR Subunits Regulates Receptor Assembly and Surface Trafficking. [PDF]

open access: yes, 2020
Nicotinic acetylcholine receptors (AChRs) are pentameric channels that mediate fast transmission at the neuromuscular junction (NMJ) and defects in receptor expression underlie neuromuscular disorders such as myasthenia gravis and congenital myasthenic ...

A Cation-π Interaction in the Binding Site of the Glycine Receptor Is Mediated by a Phenylalanine Residue [PDF]

open access: yes, 2008
Cys-loop receptor binding sites characteristically contain many aromatic amino acids. In nicotinic ACh and 5-HT3 receptors, a Trp residue forms a cation-{pi} interaction with the agonist, whereas in GABAA receptors, a Tyr performs this role.

Loop B is a major structural component of the 5-HT3 receptor [PDF]

open access: yes, 2008
The 5-HT3 receptor belongs to a family of therapeutically important neurotransmitter-gated receptors whose ligand binding sites are formed by the convergence of six peptide loops (A-F).
