Streptomyces parvulus : kynurenine formamidase I Inferred from experiment
kynurenine formamidase II Inferred from experiment

In Pathway: L-tryptophan degradation to 2-amino-3-carboxymuconate semialdehyde , L-tryptophan degradation I (via anthranilate) , L-tryptophan degradation XI (mammalian, via kynurenine)

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.
