| description | Mitochondrial phosphatidylglycerophosphatase (PGP phosphatase) () dephosphorylates phosphatidylglycerolphosphate to generate phosphatidylglycerol in cardiolipin biosynthesis. Cardiolipin is a unique dimeric phosphoglycerolipid predominantly present in mitochondrial membranes. The inverted phosphatase motif includes the highly conserved DKD triad [, ]. In Saccharomyces cerevisiae, Gep4 is required for the stability of respiratory chain supercomplexes and for growth at elevated temperature, in presence of ethidium bromide or in absence of prohibitins []. Chloroplastic phosphatidylglycerophosphate phosphatase is involved in the biosynthesis of phosphatidylglycerol (PG), a phosphoglycerolipid present in chloroplastic thylakoid membranes and has a photosynthetic function []. |
