Phosphatase Family Gene

**Semantic type:** Gene or Genome

**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)
