In enzymology, a peptidoglycan glycosyltransferase () is an enzyme that catalyzes the chemical reaction : ()n- diphosphoundecaprenol + GlcNAc-(1->4)-Mur2Ac(oyl-L-Ala-gamma-D-Glu-L-Lys-D-Ala-D-Ala)- diphosphoundecaprenol : ⇌ : ()n+1- diphosphoundecaprenol + undecaprenyl diphosphate The 4 substrates of this enzyme are * ()n-, * diphosphoundecaprenol, * GlcNAc-(1->4)-Mur2Ac(oyl-L-Ala-gamma-D-Glu-L-Lys-D-Ala-D-Ala)-, and * diphosphoundecaprenol, whereas its 3 products are * ()n+1-, * diphosphoundecaprenol, and * undecaprenyl diphosphate. This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is undecaprenyldiphospho-(N-acetyl-D-glucosaminyl-(1->4)-(N-acetyl-D-mu ramoylpentapeptide):undecaprenyldiphospho-(N-acetyl-D-glucosaminyl-( 1->4)-N-acetyl-D-muramoylpentapeptide) disaccharidetransferase. Other names in common use include PG-II, bactoprenyldiphospho-N-acetylmuramoyl-(N-acetyl-D-glucosaminyl)-, pentapeptide:peptidoglycan, N-acetylmuramoyl-N-acetyl-D-glucosaminyltransferase, penicillin binding protein (3 or 1B), and peptidoglycan transglycosylase. This enzyme participates in peptidoglycan biosynthesis. ==Structural studies== As of late 2007, 3 structures have been solved for this class of enzymes, with PDB accession codes , , and . 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「Peptidoglycan glycosyltransferase」の詳細全文を読む スポンサード リンク
