Lipid IVA 4-amino-4-deoxy-L-arabinosyltransferase (, ''undecaprenyl phosphate-alpha-L-Ara4N transferase'', ''4-amino-4-deoxy-L-arabinose lipid A transferase'', ''polymyxin resistance protein PmrK'', ''arnT (gene)'') is an enzyme with system name ''4-amino-4-deoxy-alpha-L-arabinopyranosyl ditrans,octacis-undecaprenyl phosphate:lipid IVA 4-amino-4-deoxy-L-arabinopyranosyltransferase''. This enzyme catalyses the following chemical reaction : (1) 4-amino-4-deoxy-alpha-L-arabinopyranosyl ditrans,octacis-undecaprenyl phosphate + alpha-Kdo-(2->4)-alpha-Kdo-(2->6)-lipid A alpha-Kdo-(2->4)-alpha-Kdo-(2->6)-()-lipid A + ditrans,octacis-undecaprenyl phosphate : (2) 4-amino-4-deoxy-alpha-L-arabinopyranosyl ditrans,octacis-undecaprenyl phosphate + lipid IVA lipid IIA + ditrans,octacis-undecaprenyl phosphate : (3) 4-amino-4-deoxy-alpha-L-arabinopyranosyl ditrans,octacis-undecaprenyl phosphate + alpha-Kdo-(2->4)-alpha-Kdo-(2->6)-lipid IVA 4'-alpha-L-Ara4N-alpha-Kdo-(2->4)-alpha-Kdo-(2->6)-lipid IVA + ditrans,octacis-undecaprenyl phosphate This integral membrane protein is present in the inner membrane of certain Gram negative endobacteria. == References == 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「Lipid IVA 4-amino-4-deoxy-L-arabinosyltransferase」の詳細全文を読む スポンサード リンク
