Tryptophan side chain oxidase
WebOct 1, 1991 · Two key enzyme activities were found to be involved: tryptophan side chain oxidase (TSO) and tryptophan transaminase. TSO was induced in the stationary growth phase. By fractionation of a cell extract of strain CHA0 on DEAE-Sepharose, two distinct peaks of constitutive tryptophan transaminase activity were detected. WebElectron (or hole) hopping in proteins can involve a series of redox cofactors as in Complex I (NADH dehydrogenase) of the mitochondrial respiratory chain (15–17).The side chains of select amino acids also can serve as waystations for redox hopping reactions, with Cys, Met, Trp, and Tyr being the most likely candidates ().Hole transfer reactions are more common …

It was later found that TSO is composed of two kinds of …
WebJul 13, 2024 · In addition to the aliphatic amidase, there are 14 aldehyde dehydrogenases (EC1.2.1.3.) which convert indole-3-acetaldehyde to IAA. The conversion of indole-3-acetaldehyde to indoleacetate is present in three of the known IAA pathways, including the IPyA, the tryptophan side-chain oxidase (TSO), and the tryptamine (TAM) pathways .
