Abstract. 1-Acyl-sn-glycerolphosphate acyltransferase (designated as PlsC in bacteria) catalyzes the acylation of lysophosphatidic acid and is responsible for the de novo production of phosphatidic acid, a precursor for the synthesis of various membrane e PlsC is an integral membrane protein, it is generally difficult to solubilize it without causing its Cited by: 4.

Protein acyltransferases (PATs) transfer a palmitoyl moiety derived from palmitoyl-CoA to a free thiol of a substrate protein to create a labile thioester linkage.

Biochemical characterization and kinetic analysis of this new family of enzymes requires methods to purify PATs and their substrates, as well as methods to assay PAT by: Purification of PAT from rat livers.

Our purification protocol was considerably different than previous methods and took advantage of new knowledge and reagents for protein palmitoylation.

We started with a plasma membrane fraction from rat livers because PAT activity toward G proteins is enriched in the plasma membrane fraction. The Cited by: Phospholipid remodeling involves phospholipase activity to remove acyl chains and acyltransferases to replace acyl chains.

During intestinal fat absorption, luminal lipolytic products are absorbed across the microvillus border of the enterocyte. Inside the cell, lipolytic products are reesterified and assembled with apolipoproteins to yield chylomicrons, which are released at the basolateral membrane and enter the blood stream via the lymph (Black, ; Davidson, ).Cited by: 4.

In enzymology, a 1-acylglycerolphosphate O-acyltransferase (EC ) is an enzyme that catalyzes the chemical reaction. acyl-CoA + 1-acyl-sn-glycerol 3-phosphate ⇌ CoA + 1,2-diacyl-sn-glycerol 3-phosphate.

Thus, the two substrates of this enzyme are acyl-CoA and 1-acyl-sn-glycerol 3-phosphate, whereas its two products are CoA and 1,2-diacyl-sn-glycerol : BRENDA entry. The MBOAT enzyme family, identified incomprises 11 genes in the human genome that participate in a variety of biological processes.
