KEGG ENZYME: 2.6.1.119

ENZYME: 2.6.1.119

Entry

EC 2.6.1.119                Enzyme

Name

vanillin aminotransferase;
VAMT (gene name)

Class

Transferases;
Transferring nitrogenous groups;
Transaminases

Sysname

L-alanine:vanillin aminotransferase

Reaction(IUBMB)

L-alanine + vanillin = pyruvate + vanillylamine [RN:R12622]

Reaction(KEGG)

R12622

Substrate

L-alanine [CPD:C00041];
vanillin [CPD:C00755]

Product

pyruvate [CPD:C00022];
vanillylamine [CPD:C16666]

Comment

The enzyme participates in the biosynthesis of capsaicinoids in pungent cultivars of Capsicum sp. In vivo it has only been assayed in the reverse direction, where the preferred amino group acceptors were found to be pyruvate and oxaloacetate.
