ENZYME: 4.1.1.72

Entry

EC 4.1.1.72                 Enzyme

Name

branched-chain-2-oxoacid decarboxylase;
branched-chain oxo acid decarboxylase;
branched-chain alpha-keto acid decarboxylase;
branched-chain keto acid decarboxylase;
BCKA;
(3S)-3-methyl-2-oxopentanoate carboxy-lyase

Class

Lyases;
Carbon-carbon lyases;
Carboxy-lyases

Sysname

(3S)-3-methyl-2-oxopentanoate carboxy-lyase (2-methylbutanal-forming)

Reaction(IUBMB)

(3S)-3-methyl-2-oxopentanoate = 2-methylbutanal + CO2 [RN:R03894]

Reaction(KEGG)

R03894

Substrate

(3S)-3-methyl-2-oxopentanoate [CPD:C00671]

Product

2-methylbutanal [CPD:C02223];
CO2 [CPD:C00011]

Comment

Acts on a number of 2-oxo acids, with a high affinity towards branched-chain substrates. The aldehyde formed may be enzyme-bound, and may be an intermediate in the bacterial system for the biosynthesis of branched-chain fatty acids.
