CC -!- FUNCTION: Catalyzes the synthesis of N-((2S)-2-amino-2-carboxyethyl)-L-
CC glutamate (ACEGA) from O-phospho-L-serine and L-glutamate. Involved in
CC the biosynthesis of L-2,3-diaminopropionic acid (L-Dap), a precursor of
CC staphyloferrin B and antibiotics. {ECO:0000250|UniProtKB:A6QDA0}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-glutamate + O-phospho-L-serine = H(+) + N-[(2S)-2-amino-2-
CC carboxyethyl]-L-glutamate + phosphate; Xref=Rhea:RHEA:52384,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:29985, ChEBI:CHEBI:43474,
CC ChEBI:CHEBI:57524, ChEBI:CHEBI:134610; EC=2.5.1.140;
CC Evidence={ECO:0000250|UniProtKB:A6QDA0};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000250|UniProtKB:A6QDA0};
CC -!- PATHWAY: Siderophore biosynthesis. {ECO:0000250|UniProtKB:A6QDA0}.
CC -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:A6QDA0}.
CC -!- INDUCTION: Up-regulated under iron-deficient growth conditions.
CC Repressed by Fur under iron-rich growth conditions.
CC {ECO:0000250|UniProtKB:Q2G1N3}.
CC -!- SIMILARITY: Belongs to the cysteine synthase/cystathionine beta-
CC synthase family. SbnA subfamily. {ECO:0000305}.
