General annotation (Comments)

Function	This enzyme confers resistance to kanamycin, gentamicin, dibekacin, sisomicin, neomycin and tobramycin by adenylating the 2''-hydroxyl group of these antibiotics.
Catalytic activity	Nucleoside triphosphate + gentamicin = diphosphate + 2''-nucleotidylgentamicin.
