Description N-(1-amino-1-carboxyl-2-ethyl)-glutamate synthase (2.5.1.-)
Alternative names SbnA;
ACEGA synthase;
L-2,3-diaminopropionate synthase, protein A
Catalyzed reaction O-phospho-L-serine + L-glutamate = N-(1-amino-1-carboxyl-2-ethyl)-glutamate + phosphate
Cofactor Pyridoxal phosphate.
SbnA uses O-phospho-L-serine and L-glutamate to produce the unusual metabolite N-(1-amino-1-carboxyl-2-ethyl)-glutamic acid (ACEGA), which in turn is oxidatively hydrolyzed by a second protein (SbnB) to yield α-ketoglutarate and L-2,3-diaminopropionic acid. In Staphylococcus aureus, the SbnA reaction is the first in the synthesis of the siderophore staphyloferrin B.
