A subclass of transferases (EC subclass 2.7) transferring phosphorus-containing groups. Phosphotransferases include the "kinases" (2.7.1) transferring phosphate to alcohols, to carboxyl groups (2.7.2), to nitrogenous groups (2.7.3), or to another phosphate group (2.7.4). Phosphomutases (5.4.2) catalyze apparent intramolecular transfers; pyrophosphokinases (2.7.6) catalyze transfer of the pyrophosphate group; nucleotidyltransferases (2.7.7) catalyze transfer of the nucleotide (nucleotidyl) groups (including polyribonucleotide nucleotidyltransferase) and other similar groups (2.7.8).
Synonym(s): transphosphatases
