| description | Phosphatidylserine decarboxylase plays a pivotal role in the synthesis of phospholipid by the mitochondria. The substrate phosphatidylserine is synthesized extramitochondrially and must be translocated to the mitochondria prior to decarboxylation []. Phosphatidylserine decarboxylases is responsible for conversion of phosphatidylserine to phosphatidylethanolamine and plays a central role in the biosynthesis of aminophospholipids [].Phosphatidylserine decarboxylases (PSDs) have been classified in two types. Type I PSDs include enzymes of eukaryotic mitochondria and bacterial origin which contain the amino acid sequence LGST as a characteristic motif. Type II PSDs are found in the endomembrane system of eukaryotes and contain a typical GGST motif. These characteristic motifs are considered as autocatalytic cleavage sites where proenzymes are split into alpha and beta subunits []. |
