AadA adenylates the 3''-hydroxyl group of the streptomycin glucosamine ring and the 9-hydroxyl group of the spectinomycin actinamine ring, mediating bacterial resistance to these antibiotics. This enzyme is organised into two domains: a N-terminal domain with a nucleotidyltransferase fold (Pfam:PF01909) and a C-terminal domain (this entry) which consists of five alpha-helices forming an up-and-down alpha-helical bundle. This domain undergoes small conformational changes upon binding of ATP and magnesium that play a key role in the binding of the antibiotic compounds [1,2].

This family includes kanamycin nucleotidyltransferase (KNTase) which is a plasmid-coded enzyme responsible for some types of bacterial resistance to aminoglycosides. KNTase in-activates antibiotics by catalysing the addition of a nucleotidyl group onto the drug.
