ID   2.5.1.119
DE   beta-(isoxazolin-5-on-4-yl)-L-alanine synthase.
CA   isoxazolin-5-one + O-acetyl-L-serine = 3-(5-oxoisoxazolin-4-yl)-L-alanine
CA   + acetate + H(+).
CC   -!- 3-(5-oxoisoxazolin-4-yl)-L-alanine is an antifungal antibiotic
CC       produced by the bacterium Streptomyces platensis.
CC   -!- The enzymes from the plants Lathyrus odoratus (sweet pea), L.sativus
CC       (grass pea) and Citrullus vulgaris (watermelon) that catalyze
CC       EC 2.5.1.118 also catalyze this reaction in vitro, but not in vivo.
CC   -!- Closely related and possibly identical to EC 2.5.1.47 and
CC       EC 2.5.1.51.
