Medical Definition of Transphosphatases
1.
A rather large group of enzymes that transfers a phosphate group from a donor to an acceptor. They are important in metabolism and comprise not only those transferring phosphate but also diphosphate, nucleotidyl residues, and others. These have also been subdivided according to the acceptor group.
Registry number: EC 2.7
Alcohol group acceptor: A group of enzymes that transfers a phosphate group onto an alcohol group acceptor.
Registry number: EC 2.7.1
Carboxyl group acceptor: A class of enzymes that transfers phosphate groups and has a carboxyl group as an acceptor.
Registry number: EC 2.7.2
Nitrogenous group acceptor: A group of enzymes that catalyses the transfer of a phosphate group onto a nitrogenous group acceptor.
Registry number: EC 2.7.3
Paired acceptors: A group of enzymes that transfers two phosphate groups from a donor such as ATP to two different acceptors.
Registry number: EC 2.7.9
Phosphate group acceptor: A group of enzymes that catalyses the transfer of a phosphate group onto a phosphate group acceptor.
Registry number: EC 2.7.4
Phosphomutases: A group of enzymes that catalyze an intramolecular transfer of a phosphate group. It has been shown in some cases that the enzyme has a functional phosphate group, which can act as the donor. These were previously listed under phosphotransferases (ec 2.7.-).
Registry number: EC 5.4.2
