| Comments |
Catalyses two steps in the biosynthesis of the side chain of the aminoglycoside antibiotics of the butirosin family. The enzyme adds one molecule of?L-glutamate to a dedicated acyl-carrier protein, and following decarboxylation of the product by EC?4.1.1.95,?L-glutamyl-[BtrI acyl-carrier protein] decarboxylase, adds a second?L-glutamate molecule. Requires Mg2+?or Mn2+, and activity is enhanced in the presence of Mn2+. |
| Cofactor |
Mn2+?or?Mg2+ |

| Reactions |
(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-(L-gamma-glutamylamino)butanoyl-[BtrI acyl-carrier protein]. |
