ID   2.5.1.50
DE   zeatin 9-aminocarboxyethyltransferase.
AN   beta-(9-cytokinin)alanine synthase.
AN   beta-(9-cytokinin)-alanine synthase.
AN   lupinate synthetase.
AN   lupinic acid synthase.
AN   lupinic acid synthetase.
AN   O-acetyl-L-serine acetate-lyase (adding N(6)-substituted adenine).
CA   O-acetyl-L-serine + zeatin = acetate + H(+) + L-lupinate.
CC   -!- The enzyme acts not only on zeatin but also on other N(6)-substituted
CC       adenines.
CC   -!- The reaction destroys their cytokinin activity and forms the
CC       corresponding 3-(adenin-9-yl)-L-alanine.
CC   -!- Formerly EC 4.2.99.13.
