sxta
Description 4-amino-3-oxo-guandidinoheptane synthase (2.3.1.-)
Alternative names SxtA AONS domain
Catalyzed reaction propionyl-[acyl-carrier protein] + L-arginine = 4-amino-3-oxo-guandidinoheptane + acyl-carrier protein + CO(2).
Cofactor Pyridoxal-phosphate
Comments The enzyme is a C-terminal OAS domain of a four-domain polyketide-like synthase, SxtA, and catalyzes a C-C bond formation between the alpha-carbon of L-arginine and thioester carbon of the propionyl-ACP, in the saxitoxin biosynthesis. The activity is very similar to 8-amino-7-oxononanoate synthase (EC 2.3.1.47)
