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. a fatty acyl-[ACP] + phosphate = an acyl phosphate + holo-[ACP] Lipid metabolism; phospholipid metabolism. Homodimer. Probably interacts with PlsY. Associated with the membrane possibly through PlsY. Belongs to the PlsX family. Could be the product of a pseudogene. Resulting from truncation by frameshift mutation.
