Enzyme Commission Summary:
A membrane protein. Uses CoA derivatives of palmitate, stearate and oleate, with highest activity on palmitoyl-CoA.
Instance reactions of [a long-chain acyl-CoA + sn-glycerol 3-phosphate → a 1-acyl-sn-glycerol 3-phosphate + coenzyme A] (126.96.36.199):
i1: hexadecanedioyl-CoA + sn-glycerol 3-phosphate = 1-C16:0-α,ω-dicarboxyl-2-lysophosphatidate + coenzyme A (188.8.131.52)
i2: 18-hydroxyoleoyl-CoA + sn-glycerol 3-phosphate → 1-[18-hydroxyoleyl]-2-lyso-phosphatidate + coenzyme A (184.108.40.206)
