NCIt definition : A Phosphotransferase Gene encodes one of a large group of enzymes that transfer phosphate,
diphosphate, nucleotidyl residues, and other groups. Many phosphotransferases catalyze
the conversion of a proenzyme to an active enzyme or catalyze the transfer of phosphate
groups to form triphosphates (e.g., ATP). Phosphotransferases have also been subdivided
according to the acceptor group.;
