Enzyme Information

6.1.2.2

Nebramycin 5' synthase.

based on mapping to UniProt Q70IY1

(1) Tobramycin + carbamoyl phosphate + ATP + H(2)O = nebramycin 5' + AMP + diphosphate + phosphate. (2) Kanamycin A + carbamoyl phosphate + ATP + H(2)O = 6''-O- carbamoylkanamycin A + AMP + diphosphate + phosphate.

-!- The enzyme from the bacterium Streptoalloteichus tenebrarius catalyzes the activation of carbamoyl phosphate to O-carbamoyladenylate and the subsequent carbamoylation of kanamycin and tobramycin. -!- Formerly EC 2.1.3.13 and EC 2.1.3.14.
