Enzyme Information

4.1.1.74
Indolepyruvate decarboxylase.
based on mapping to UniProt P06169
3-(indol-3-yl)pyruvate = 2-(indol-3-yl)acetaldehyde + CO(2).
-!- More specific than EC 4.1.1.1.
4.1.1.-
Carboxy-lyases.
based on mapping to UniProt P06169
4.1.1.72
Branched-chain-2-oxoacid decarboxylase.
based on mapping to UniProt P06169
(3S)-3-methyl-2-oxopentanoate = 2-methylbutanal + CO(2).
-!- Acts on a number of 2-oxo acids, with a high affinity toward branched-chain substrates. -!- The aldehyde formed may be enzyme-bound, and may be an intermediate in the bacterial system for biosynthesis of branched-chain fatty acids.
4.1.1.43
Phenylpyruvate decarboxylase.
based on mapping to UniProt P06169
Phenylpyruvate = phenylacetaldehyde + CO(2).
-!- Also acts on (indol-3-yl)pyruvate.
