IUBMB Enzyme Nomenclature


Accepted name: N-(2-amino-2-carboxyethyl)-L-glutamate synthase

Reaction: O-phospho-L-serine + L-glutamate = N-[(2S)-2-amino-2-carboxyethyl]-L-glutamate + phosphate

Other name(s): SbnA; ACEGA synthase

Systematic name: O-phospho-L-serine:L-glutamate N-(2S)-2-amino-2-carboxyethyltransferase

Comments: The enzyme, characterized from the bacterium Staphylococcus aureus, is involved in the biosynthesis of the siderophore staphyloferrin B.
