In enzymology, a macrolide 2'-kinase () is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are ATP and oleandomycin, whereas its two products are ADP and oleandomycin 2'-O-phosphate.
This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor. The systematic name of this enzyme class is ATP:macrolide 2'-O-phosphotransferase.
