This domain is found at the C-terminal end of Aminoglycoside adenylyltransferase from Salmonella typhimurium (AadA) and other proteins associated with methicillin-resistant bacteria. 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].	Domain

Members of this family belong to a large family of nucleotidyltransferases [1]. 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.	Domain
