Enzymatic synthesis of two isoxazolylalanine isomers by cysteine synthases in Lathyrus species

Two isoxazolylalanine isomers, β-(isoxazolin-5-on-2-yl)-L-alanine (BIA, 1) and β-(isoxazolin-5-on-4-yl)-L-alanine (TAN-950 A, 2) were confirmed to be derived from O-acetyl-L-serine (OAS) and isoxazolin-5-one by cysteine synthases (CSases) with a different ratio in different plant parts. Some properties of this enzyme in the biosynthesis of both isomers are described.
