产品内容
本酶催化的反应为(1) 1-Palmitoyl-2-Acyl-Sn-Glycero-3-Phosphocholine + Hexa-Acyl Lipid A = 2-Acyl-Sn-Glycero-3-Phosphocholine + Hepta-Acyl Lipid A;;(2) 1-Palmitoyl-2-Acyl-Sn-Glycero-3-Phosphocholine + Lipid IIA = 2-Acyl-Sn-Glycero-3-Phosphocholine + Lipid IIB;;(3) 1-Palmitoyl-2-Acyl-Sn-Glycero-3-Phosphocholine + Lipid IVA = 2-Acyl-Sn-Glycero-3-Phosphocholine + Lipid IVB，系统名称为1-Palmitoyl-2-Acyl-Sn-Glycero-3-Phosphocholine:lipid-IVA Palmitoyltransferase，从细菌大肠杆菌 Escherichia coli 和鼠伤寒沙门菌 Salmonella typhimurium 中分离得到。该酶偏好sn-1位带棕榈酰基、sn-2位带棕榈酰或硬脂酰基的磷脂酰胆碱。对相应的磷脂酰丝氨酸有一定活性，但对其他二酰磷脂化合物仅有微弱活性。该酶还作用于Kdo-(2->4)-Kdo-(2->6)-脂质IVA。
