1.FabB(β-ketoacyl-acyl carrier protein synthaseⅠ)and FabF(β-ketoacyl-acyl carrier protein synthaseⅡ)are two key enzymes of fatty acid biosynthesis in E.体内体外研究显示:fabF1基因能互补大肠杆菌fabB突变,FabF1具有β酮脂酰ACP合成酶Ⅰ(FabB)活性;fabF2能互补大肠杆菌fabF突变,FabF2具有β酮脂酰...
例如由牛肝线粒体制得的硫解酶可作用于C4~C16的β-酮脂酰CoA;线粒体外的硫解酶可作用于短链的底物。虽然该酶催化反应是可逆的,但由于早酮脂酰辅酶A硫解酶催化硫解作用是高度放能反应,所以整个反应平衡点偏向于裂解方向,难以进行逆向反应。有时也把乙酰CoA-乙酰基转移酶和乙酰基CoA酰基转移酶等包括在硫解...
