to 2.5 A resolution. AadA consists of a nucleotidyltransferase domain and an alpha-helical bundle domain. AadA crystallizes as a monomer. ATP binding has to occur before binding of the aminoglycoside substrate, and ATP binding repositions the two domains for aminoglycoside binding in the interdomain cleft
