Phosphotransferases are a category of enzymes (EC number 2.7) that catalyze phosphorylation reactions. The general form of the reactions they catalyze is: A-P + B B-P + A Where ''P'' is a phosphate group and A and B are the donating and accepting molecules, respectively. ==Classification of Phosphotransferases== Phosphotransferases are generally classified according to the acceptor molecule.〔() Phosphotransferases are any enzyme of sub‐subclasses EC 2.7.1 to 2.7.4, and EC 2.7.9〕〔(), Classification in this article follows the rules of Enzyme Nomenclature of the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology (NC-IUBMB).〕 *EC 2.7.1 Phosphotransferases with an alcohol group as acceptor *EC 2.7.2 Phosphotransferases with a carboxy group as acceptor *EC 2.7.3 Phosphotransferases with a nitrogenous group as acceptor *EC 2.7.4 Phosphotransferases with a phosphate group as acceptor *EC 2.7.9 Phosphotransferases with paired acceptors. In these reactions, a single triphosphate-nucleotide transfers two phosphates to two different acceptor molecules, resulting in a monophosphate-nucleotide and two phosphorylated products. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Phosphotransferase」の詳細全文を読む スポンサード リンク
