IUBMB Enzyme Nomenclature


Accepted name: aminoglycoside 3-N-acetyltransferase

Reaction: acetyl-CoA + a 2-deoxystreptamine antibiotic = CoA + N3-acetyl-2-deoxystreptamine antibiotic

Glossary: kanamycin

Other name(s): 3-aminoglycoside acetyltransferase; 3-N-aminoglycoside acetyltransferase; aminoglycoside N3-acetyltransferase; acetyl-CoA:2-deoxystreptamine-antibiotic N3'-acetyltransferase (incorrect); aminoglycoside N3'-acetyltransferase (incorrect)

Systematic name: acetyl-CoA:2-deoxystreptamine-antibiotic N3-acetyltransferase

Comments: Different from EC gentamicin 3-N-acetyltransferase. A wide range of antibiotics containing the 2-deoxystreptamine ring can act as acceptors, including gentamicin, kanamycin, tobramycin, neomycin and apramycin.
