IUBMB Comments
O3-acetyl-L-serine:uracil 1-(2-amino-2-carboxyethyl)transferase
The enzyme produces the non-proteinogenic amino acid L-willardiine, which is naturally found in the plants Acacia willardiana, Mimosa pigra, and Pisum sativum (pea). The enzyme from Pisum species also produces L-isowillardiine. Not identical with EC 2.5.1.47 cysteine synthase.
