EC Number: 18.104.22.168
Enzymes and Genes:
tryptophan side chain oxidase / tryptophan 2'-dioxygenase ( Pseudomonas fluorescens )
The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.
Most BioCyc compounds have been protonated to a reference pH value of 7.3, and some reactions have been computationally balanced for hydrogen by adding free protons. Please see the PGDB Concepts Guide for more information.
Mass balance status: Balanced.
Enzyme Commission Primary Name: tryptophan 2′-dioxygenase
Enzyme Commission Synonyms: indole-3-alkane α-hydroxylase, tryptophan side-chain α,β-oxidase, tryptophan side chain oxidase II, tryptophan side-chain oxidase, TSO, indolyl-3-alkan α-hydroxylase, tryptophan side chain oxidase type I, TSO I , TSO II, tryptophan side chain oxidase
Standard Gibbs Free Energy (ΔrG'° in kcal/mol): -109.23899 [Latendresse13]
Enzyme Commission Summary:
A hemoprotein. Acts on a number of indole-3-alkane derivatives, oxidizing the 3-side-chain in the 2'-position. Best substrates were L-tryptophan and 5-hydroxy-L-tryptophan.
