1.13.99.3 |
Accepted name: |
tryptophan 2′-dioxygenase |
Reaction: |
L-tryptophan + O2 = (indol-3-yl)glycolaldehyde + CO2 + NH3 |
Other name(s): |
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 |
Systematic name: |
L-tryptophan:oxygen 2′-oxidoreductase (side-chain-cleaving) |
Comments: |
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. |
