Glossary: O-acetyl-L-serine = (2S)-3-acetyloxy-2-aminopropanoic acid
L-mimosine = (2S)-2-amino-3-(3-hydroxy-4-oxopyridin-1(4H)-yl)propanoic acid

Other name(s): O3-acetyl-L-serine acetate-lyase (adding 3,4-dihydroxypyridin-1-yl)

Systematic name: O-acetyl-L-serine:3,4-dihydroxypyridine 1-(2-amino-2-carboxyethyl)transferase

Comments: Brings about the biosynthesis of L-mimosine in Mimosa and Leucaena sp. Not identical with EC β-pyrazolylalanine synthase.
