Accepted name: O-ureido-L-serine synthase
Reaction: O-acetyl-L-serine + hydroxyurea = O-ureido-L-serine + acetate
Glossary: O-ureido-L-serine = (2S)-2-amino-3-[(carbamoylamino)oxy]propanoate
O-acetyl-L-serine = O3-acetyl-L-serine = (2S)-3-acetyloxy-2-aminopropanoic acid
Other name(s): dcsD (gene name)
Systematic name: O-acetyl-L-serine:hydroxyurea 2-amino-2-carboxyethyltransferase
Comments: The enzyme participates in the biosynthetic pathway of D-cycloserine, an antibiotic substance produced by several Streptomyces species. Also catalyses EC, cysteine synthase.
