2.7.7.41 | evolution | isoforms of CDS are located in plastids, mitochondria and the endomembrane system of plants and are encoded by five genes in Arabidopsis. Two genes have previously been shown to code for the plastidial isoforms which are indispensable for the biosynthesis of plastidial phosphatidylglycerol, and thus biogenesis and function of thylakoid membranes. the extraplastidial CDS isoforms, encoded by CDS1 and CDS2 which are constitutively expressed contrary to CDS3. These closely related CDS genes code for membrane proteins located in the endoplasmic reticulum and possess very similar enzymatic properties | Arabidopsis thaliana |
2.7.7.41 | malfunction | the seedling lethal phenotype of the cds1cds2 double mutant shows that plant cells require at least one catalytically active microsomal CDS isoform for cell division and expansion. According to the altered glycerolipid composition of the double mutant in comparison with wild-type seedlings, it is likely that the drastic decrease in the level of phosphatidylinositol and the increase in phosphatidic acid cause defects in cell division and expansion. The cds1cds2 double mutant is seedling lethal, phenotypes, overview. The seedling-lethal phenotype of cds1cds2 double mutants can be rescued by inducing the expression of a functional CDS1 or CDS2 gene | Arabidopsis thaliana |
2.7.7.41 | physiological function | Arabidopsis mutants lacking either one or both CDS1 and CDS2 genes clearly show that these two genes have redundant functions. As reflected in the seedling lethal phenotype of the cds1cds2 double mutant, plant cells require at least one catalytically active microsomal CDS isoform for cell division and expansion | Arabidopsis thaliana |
2.7.7.41 | physiological function | cytidine diphosphate diacylglycerol synthase (CDS) catalyzes the activation of phosphatidic acid to CDP-diacylglycerol, a central intermediate in glycerolipid biosynthesis in prokaryotic and eukaryotic organisms. CDP-diacylglycerol is the precursor to phosphatidylinositol, phosphatidylglycerol, and cardiolipin of eukaryotic phospholipids that are essential for various cellular functions | Arabidopsis thaliana |
