SYSTEMATIC NAME

IUBMB Comments

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

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.
