2.0 2015-09-08 20:29:04 -0600 2015-09-16 17:35:14 -0600 ECMDB24912 M2MDB007029 CL(19:iso/19:0cycv8c/19:0/19:0) CL(19:iso/19:0cycv8c/19:0/19:0) is a cardiolipin (CL). Cardiolipins are sometimes called a 'double' phospholipid because they have four fatty acid tails, instead of the usual two. CL(19:iso/19:0cycv8c/19:0/19:0) contains one chain of 17-methylocatdecanoic acid at the C1 position, one chain of (heptadec-11-12-cyclo-anoyl) at the C2 position, two chains of nonadecanoic acid at the C3 and C4 positions. While the theoretical charge of cardiolipins is -2, under normal physiological conditions (pH near 7), the molecule may carry only one negative charge. In prokaryotes such as E. coli, the enzyme known as diphosphatidylglycerol synthase catalyses the transfer of the phosphatidyl moiety of one phosphatidylglycerol to the free 3'-hydroxyl group of another, with the elimination of one molecule of glycerol. In E. coli, which acylates its glycerophospholipids with acyl chains ranging in length from 12 to 19 carbons and possibly containing an unsaturation, or a cyclopropane group more than 100 possible CL molecular species are theoretically possible. E. coli membranes consist of ~5% cardiolipin (CL), 20-25% phosphatidylglycerol (PG), and 70-80% phosphatidylethanolamine (PE) as well as smaller amounts of phosphatidylserine (PS). CL is distributed between the two leaflets of the bilayers and is located preferentially at the poles and septa in E. coli and other rod-shaped bacteria. It is known that the polar positioning of the proline transporter ProP and the mechanosensitive ion channel MscS in E. coli is dependent on CL. It is believed that cell shape may influence the localization of CL and the localization of certain membrane proteins.

The major phospholipids of E. coli are phosphatidylethanolamine, phosphatidylglycerol and cardiolipin. All phospholipids contain sn-glycerol-3-phosphate esterified with fatty acids at the sn-1 and sn-2 positions. The reaction starts from a glycerone phosphate (dihydroxyacetone phosphate) produced in glycolysis. The glycerone phosphate is transformed to a sn-glycerol 3-phosphate (glycerol 3 phosphate) by NADPH driven glycerol-3-phosphate dehydrogenase. Sn-glycerol 3-phosphate is transformed to a 1-acyl-sn-glycerol 3-phosphate(1-oleyl-2-lyso-phosphatidate , 1-palmitoylglycerol 3-phosphate , 1-stearoyl-sn-glycerol 3-phosphate). This can be achieve by a sn-glycerol-3-phosphate 1-0-acyltransferase that interacts either with a long-chain acyl-CoA or with an acyl-[acp]. The 1-acyl-sn-glycerol 3-phosphate is transformed into a 1,2-diacyl-sn-glycerol 3-phosphate through a 1-acylglycerol-3-phosphate O-acyltransferase. This compound is then converted into a CPD-diacylglycerol through a CTP (phosphatidate cytididyltransferase. CPD-diacylglycerol can be transformed either to a L-1-phosphatidylserine or a L-1-phosphatidylglycerol-phosphate through a phosphatidylserine synthase or a phosphatidylglycerophosphate synthase respectively. The L-1-phosphatidylserine transforms into L-1-phosphatidylethanolamine through a phosphatidylserine decarboxylase, o the other hand L-1-phosphatidylglycerol-phosphate gets transformed into a L-1-phosphatidyl-glycerol through a phosphatidylglycerophosphatase. These 2 products combines produce a cardiolipin and a ethanolamine. The L-1 phosphatidyl-glycerol can also interact with cardiolipin synthase resulting in a glycerol and a cardiolipin.
