Protein

1-acyl-sn-glycerol-3-phosphate acyltransferase epsilon

Gene

Agpat5

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: -Experimental evidence at transcript leveli

Functioni

Converts lysophosphatidic acid (LPA) into phosphatidic acid by incorporating an acyl moiety at the sn-2 position of the glycerol backbone. Acts on LPA containing saturated or unsaturated fatty acids C15:0-C20:4 at the sn-1 position using C18:1-CoA as the acyl donor. Also acts on lysophosphatidylethanolamine using oleoyl-CoA, but not arachidonoyl-CoA, and lysophosphatidylinositol using arachidonoyl-CoA, but not oleoyl-CoA. Activity toward lysophosphatidylglycerol not detectable.1 Publication

Caution

It is uncertain whether Met-1 or Met-12 is the initiator.Curated

Catalytic activityi

Acyl-CoA + 1-acyl-sn-glycerol 3-phosphate = CoA + 1,2-diacyl-sn-glycerol 3-phosphate.

Pathwayi: CDP-diacylglycerol biosynthesis

This protein is involved in step 2 of the subpathway that synthesizes CDP-diacylglycerol from sn-glycerol 3-phosphate.
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. Glycerol-3-phosphate acyltransferase 1, mitochondrial (Gpam), Glycerol-3-phosphate acyltransferase 4 (Gpat4), Glycerol-3-phosphate acyltransferase 3 (Gpat3), Glycerol-3-phosphate acyltransferase 2, mitochondrial (Gpat2)
  2. 1-acyl-sn-glycerol-3-phosphate acyltransferase gamma (Agpat3), 1-acyl-sn-glycerol-3-phosphate acyltransferase beta (Agpat2), 1-acyl-sn-glycerol-3-phosphate acyltransferase alpha (Agpat1), Lysocardiolipin acyltransferase 1 (Lclat1), 1-acyl-sn-glycerol-3-phosphate acyltransferase epsilon (Agpat5), 1-acyl-sn-glycerol-3-phosphate acyltransferase delta (Agpat4)
  3. Phosphatidate cytidylyltransferase, mitochondrial (Tamm41), Phosphatidate cytidylyltransferase, mitochondrial (Tamm41), Phosphatidate cytidylyltransferase (Cds2), Phosphatidate cytidylyltransferase (Cds2), Phosphatidate cytidylyltransferase 2 (Cds2), Phosphatidate cytidylyltransferase (Cds2), Phosphatidate cytidylyltransferase 1 (Cds1)
This subpathway is part of the pathway CDP-diacylglycerol biosynthesis, which is itself part of Phospholipid metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes CDP-diacylglycerol from sn-glycerol 3-phosphate, the pathway CDP-diacylglycerol biosynthesis and in Phospholipid metabolism.
