Description 2-amino-5,7-dihydroxy-6-keto-heptanoic-[Vzb22 amino carrier protein] transaminase (2.6.1.-)
Alternative names Vzb9 (gene name)
Catalyzed reaction 2-amino-5,7-dihydroxy-6-keto-heptanoic-[Vzb22 amino carrier protein] + L-glutamate = 2,6-diamino-5,7-dihydroxy-heptanoic acid-[Vzb22 amino carrier protein] + 2-oxoglutarate.
Cofactor Pyridoxal-phosphate
Comments The enzyme from Streptomyces sp. SANK 60404 is involved in the biosynthetic pathway of vazabitide A. Vazabitide A derives from the nonproteinogenic amino acid (2S,6R)-diamino-(5R,7)-dihydroxy-heptanoic acid (DADH). The product of Vzb9, DADH-[Vzb22 amino carrier protein], follows hydrolysis by Vzb26 to release DADH.

The activity is similar to L-glutamine:2-deoxy-scyllo-inosose aminotransferase (2.6.1.100)
