Phosphotransferases: A rather large group of enzymes comprising not only those transferring phosphate but also diphosphate, nucleotidyl residues, and others. These have also been subdivided according to the acceptor group. (From Enzyme Nomenclature, 1992) EC 2.7.Kanamycin Kinase: A class of enzymes that inactivate aminocyclitol-aminoglycoside antibiotics (AMINOGLYCOSIDES) by regiospecific PHOSPHORYLATION of the 3' and/or 5' hydroxyl.Phosphotransferases (Paired Acceptors): A group of enzymes that transfers two phosphate groups from a donor such as ATP to two different acceptors. (From Enzyme Nomenclature, 1992) EC 2.7.9.Phosphotransferases (Alcohol Group Acceptor): A group of enzymes that transfers a phosphate group onto an alcohol group acceptor. EC 2.7.1.Ethanolaminephosphotransferase: An enzyme that catalyzes reversibly the transfer of phosphoethanolamine from CDP-ethanolamine to diacylglycerol to yield phosphatidylethanolamine (cephalin) and CMP. The enzyme is found in the endoplasmic reticulum. EC 220.127.116.11.Aminoglycosides: Glycosylated compounds in which there is an amino substituent on the glycoside. Some of them are clinically important ANTIBIOTICS.Diacylglycerol Cholinephosphotransferase: An enzyme that catalyzes the synthesis of phosphatidylcholines from CDPcholine and 1,2-diacylglycerols. EC 18.104.22.168.Phosphotransferases (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.-). (From Enzyme Nomenclature, 1992) EC 5.4.2.Phosphotransferases (Carboxyl Group Acceptor): A class of enzymes that transfers phosphate groups and has a carboxyl group as an acceptor. EC 2.7.2.Phosphotransferases (Nitrogenous Group Acceptor): A group of enzymes that catalyzes the transfer of a phosphate group onto a nitrogenous group acceptor. EC 2.7.3.Phosphotransferases (Phosphate Group Acceptor): A group of enzymes that catalyzes the transfer of a phosphate group onto a phosphate group acceptor. EC 2.7.4.Amino Acid Sequence: The order of amino acids as they occur in a polypeptide chain. This is referred to as the primary structure of proteins. It is of fundamental importance in determining PROTEIN CONFORMATION.Substrate Specificity: A characteristic feature of enzyme activity in relation to the kind of substrate on which the enzyme or catalytic molecule reacts.Molecular Sequence Data: Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.Kinetics: The rate dynamics in chemical or physical systems.
