Thus, the two substrates of this enzyme are nucleoside triphosphate and gentamicin, whereas its two products are diphosphate and 2''-nucleotidylgentamicin.
This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing nucleotide groups (nucleotidyltransferases). The systematic name of this enzyme class is NTP:gentamicin 2"-nucleotidyltransferase. Other names in common use include gentamicin 2"-adenylyltransferase, aminoglycoside adenylyltransferase, and gentamicin 2"-nucleotidyltransferase.
