6.3.2.47 | physiological function |
gene DdaF belongs to the dapdiamide antibiotic biosynthetic gene cluster. DdaF acts as a second ATP-dependent amide ligase, cleaving ATP to ADP and Pi during amide bond formation. DdaF adds Val, Ile, or Leu to the carboxylate of fumaramoyl-2,3-diaminopropionate to make the three dapdiamides A-C. To build the dapdiamide antibiotic scaffold, amidation must occur on the fumaroyl-diaminopropionate scaffold, after DdaG action but before DdaF catalysis |
