(1) ATP + L-glutamate + BtrI acyl-carrier protein ADP + phosphate + L-glutamyl-[BtrI acyl-carrier protein]
(2) ATP + L-glutamate + 4-amino butanoyl-[BtrI acyl-carrier protein] ADP + phosphate + 4-(gamma-L-glutamylamino)butanoyl-[BtrI acyl-carrier protein]

This enzyme catalyses two steps in the biosynthesis of the side chain of the aminoglycoside antibiotics of the butirosin family.
