Protein name

RecName: Full=Phosphate acyltransferase; EC 2.3.1.274; AltName: Full=Acyl-ACP phosphotransacylase; AltName: Full=Acyl-[acyl-carrier-protein]--phosphate acyltransferase; AltName: Full=Phosphate-acyl-ACP acyltransferase;

Gene name

plsX

Function	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.
Catalytic activity	RHEA:42292: a fatty acyl-[ACP] + phosphate = an acyl phosphate + holo-[ACP] EC 2.3.1.274
Pathway	Lipid metabolism; phospholipid metabolism.
Subunit	Homodimer. Probably interacts with PlsY.
Subcellular location	Cytoplasm. Note=Associated with the membrane possibly through PlsY.
Similarity	Belongs to the PlsX family.
