cardiolipin/arabidopsis

In eukaryotes the presence of the dimeric phospholipid cardiolipin (CL) is limited to the mitochondrial membranes. It resides predominantly in the inner membrane where it interacts with components of the mitochondrial electron transfer chain. CL deficiency has previously been shown to affect

Functional expression studies in microorganisms showed that the Arabidopsis thaliana gene At4g04870 represents the cardiolipin synthase (CLS) gene encoding a hydrophobic preprotein of 38 kDa with a cleavable signal peptide for the import into mitochondria. CLS of Arabidopsis over-expressed in

Cardiolipin (CL) is an anionic phospholipid with a dimeric structure. In eukaryotes, it is primarily localized in the inner membranes of mitochondria. Although the biosynthetic pathway of CL is well known, the gene for CL synthase has not been identified in any higher organisms. In this study, the

Cardiolipin (CL) is the signature phospholipid of the mitochondrial inner membrane. In animals and yeast (Saccharomyces cerevisiae), CL depletion affects the stability of respiratory supercomplexes and is thus crucial to the energy metabolism of obligate aerobes. In eukaryotes, the last step of CL

Mitochondria are essential and dynamic organelles in eukaryotes. Cardiolipin (CL) is a key phospholipid in mitochondrial membranes, playing important roles in maintaining the functional integrity and dynamics of mitochondria in animals and yeasts. However, CL's role in plants is just beginning to be

Cytidine diphosphate (CDP)-diacylglycerol synthase (cytidine triphosphate:phosphatidate cytihyltransferase, EC 2.7.7.41) catalyzes the formation of CDP-diacylglycerol, which is the precursor of phosphatidylinositol, phosphatidylglycerol, and cardiolipin. We report the first cloning, to our

The Arabidopsis thaliana lysophospholipid acyltransferase At1g78690 acylates a variety of lysophospholipids such as lyso phosphatidylglycerol, lyso phosphatidylethanolamine and lyso phosphatidylserine. Despite di-acylate phosphatidylglycerol being a substrate, overexpression of At1g78690 in

Cytidinediphosphate diacylglycerol synthase (CDS) catalyzes the activation of phosphatidic acid to cytidinediphosphate (CDP)-diacylglycerol, a central intermediate in glycerolipid biosynthesis in prokaryotic and eukaryotic organisms. Cytidinediphosphate-diacylglycerol is the precursor to

FTSH4 is one of the inner membrane-embedded ATP-dependent metalloproteases in mitochondria of Arabidopsis (Arabidopsis thaliana). In mutants impaired to express FTSH4, carbonylated proteins accumulated and leaf morphology was altered when grown under a short-day photoperiod, at 22°C, and a long-day

Genetic dissection of the lipid bilayer composition provides essential in vivo evidence for the role of individual lipid species in membrane function. To understand the in vivo role of the anionic phospholipid, phosphatidylglycerol, the loss-of-function mutation was identified and characterized in

Escherichia coli membranes have a substantial bilayer curvature stress due to a large fraction of the nonbilayer-prone lipid phosphatidylethanolamine, and a mutant (AD93) lacking this lipid is severely crippled in several membrane-associated processes. Introduction of four lipid glycosyltransferases
