Gentamicin 2" nucleotidyltransferase

In enzymology, a gentamicin 2"-nucleotidyltransferase (EC 2.7.7.46) is an enzyme that catalyzes the chemical reaction

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.
