Protein

CDP-diacylglycerol--glycerol-3-phosphate 3-phosphatidyltransferase, mitochondrial

Gene

PGS1

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at transcript leveli

Functioni

Functions in the biosynthesis of the anionic phospholipids phosphatidylglycerol and cardiolipin.By similarity

Caution

Catalytic activityi

CDP-diacylglycerol + sn-glycerol 3-phosphate = CMP + 3(3-sn-phosphatidyl)-sn-glycerol 1-phosphate.

Enzyme regulationi

Activated by calcium and magnesium and inhibited by other bivalent cations.By similarity

Pathwayi: phosphatidylglycerol biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes phosphatidylglycerol from CDP-diacylglycerol.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. CDP-diacylglycerol--glycerol-3-phosphate 3-phosphatidyltransferase, mitochondrial (PGS1)
  2. Phosphatidylglycerophosphatase and protein-tyrosine phosphatase 1 (PTPMT1)
This subpathway is part of the pathway phosphatidylglycerol 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 phosphatidylglycerol from CDP-diacylglycerol, the pathway phosphatidylglycerol biosynthesis and in Phospholipid metabolism.
