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

Gene

PGS1

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at transcript leveli

Functioni

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

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.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
