NCIt definition : Phosphotransferase Genes encode Phosphotransferases (Phosphatases), a large group
of enzymes subdivided according to acceptor group that transfer phosphate, diphosphate,
nucleotidyl residues, and other phosphomoieties. Some phosphotransferases catalyze
the conversion of a proenzyme to an active enzyme; others transfer phosphate groups
to form triphosphates (e.g., ATP). (NCI);
