EC 2.7 - Transferring phosphorus-containing groups

Description

This subclass contains a rather large group of enzymes that transfer not only phosphate but also diphosphate, nucleotidyl residues and other groups. The phosphotransferases are subdivided according to the acceptor group, which may be an alcohol group (EC 2.7.1), a carboxy group (EC 2.7.2), a nitrogenous group, such as that of creatine (EC 2.7.3), or a phosphate group, as in the case of adenylate kinase (EC 2.7.4). Other sub-subclasses are for: diphosphotransferases (EC 2.7.6), nucleotidyltransferases (EC 2.7.7) and transferases for other substituted phosphate groups (EC 2.7.8). With the enzymes of sub-subclass EC 2.7.9, two phosphate groups are transferred from a donor such as ATP to two different acceptors. The protein kinases are divided into the sub-subclasses protein-tyrosine kinases (EC 2.7.10), protein-serine/threonine kinases (EC 2.7.11), dual-specificity kinases (EC 2.7.12), protein-histidine kinases (EC 2.7.13) and other protein kinases (EC 2.7.99).
