Catalyzes the reversible formation of acyl-phosphate (acyl-PO(4)) from acyl-[acyl-carrier-protein] (acyl-ACP). This enzyme utilizes acyl-ACP as fatty acyl donor, but not acyl-CoA (By similarity). a fatty acyl-[ACP] + phosphate = an acyl phosphate + holo-[ACP] Lipid metabolism; phospholipid metabolism. Homodimer. Probably interacts with PlsY (By similarity). Associated with the membrane possibly through PlsY. Belongs to the PlsX family.
