== Function ==
[https://www.uniprot.org/uniprot/TOBZ_STRSD TOBZ_STRSD] TobZ is involved in the biosynthesis of the 2-deoxystreptamine-containing aminoglycoside antibiotics such as nebramycin 5 and 6-O-carbamoylkanamycin. Catalyzes the hydrolysis of carbamoyl phosphate and its subsequent adenylation by ATP to yield O-carbamoyladenylate. Then it catalyzes the transfer of the carbamoyl moiety from O-carbamoyladenylate to the tobramycin 6-hydroxy group to yield nebramycin 5. It catalyzes the same reaction with kanamycin A. These reactions are considerably slower in the presence of deoxy-ATP.<ref>PMID:20936279</ref> <ref>PMID:22383337</ref>
