Indoleamine-2,3-Dioxygenase as a Perioperative Marker of the Immune System
Frontiers in Physiology, 2021 Indoleamine-2,3-dioxygenase (IDO) is the “rate-limiting” enzyme in the kynurenine (Kyn) pathway of the tryptophan (Trp) catabolism. By its immune-modulatory effect, IDO initiates changes to the physiologically balanced immune state and plays a key role ...

Tracking the Electron Transfer Cascade in European Robin Cryptochrome 4 Mutants [PDF]
, 2022 The primary step in the elusive ability of migratory birds to sense weak Earth-strength magnetic fields is supposedly the light-induced formation of a long-lived, magnetically sensitive radical pair inside a cryptochrome flavoprotein located in the retina of these birds.

Interactions of Tryptophan, Tryptophan Peptides, and Tryptophan Alkyl Esters at Curved Membrane Interfaces [PDF]
Biochemistry, 2006 Motivated by ongoing efforts to understand the mechanism of membrane protein crystallogenesis and transport in the lipidic cubic phase, the nature of the interaction between tryptophan and the bilayer/aqueous interface of the cubic phase has been investigated.

Proton transfer in histidine-tryptophan heterodimers embedded in helium droplets [PDF]
Journal of Chemical Physics 142, 114306 (2015), 2015 We used cold helium droplets as nano-scale reactors to form and ionize, by electron bombardment and charge transfer, aromatic amino acid heterodimers of histidine with tryptophan, methyl-tryptophan, and indole. The molecular interaction occurring through an N-H...N hydrogen bond leads to a proton transfer from the indole group of tryptophan to the ...

Microbial Cell Factories, 2012 Background L-tryptophan is an aromatic amino acid widely used in the food, chemical and pharmaceutical industries. In Escherichia coli, L-tryptophan is synthesized from phosphoenolpyruvate and erythrose 4-phosphate by enzymes in the shikimate pathway and

tRNA-isoleucine-tryptophan Composite Gene [PDF]
Biochemical and biophysical Research Communications 339 (2005)
37-40, 2005 Transfer-RNA genes in archaea often have introns intervening between exon sequences. The structural motif at the boundary between exon and intron is the bulge-helix-bulge. Computational investigations of these boundary structures in H. marismortui lead us to propose that tRNA-isoleucine and tRNA-tryptophan genes are co-located.
