2.0 2012-08-23 12:32:38 -0600 2015-12-09 11:20:58 -0700 ECMDB22802 M2MDB003192 CL(17:0cycw7c/16:0/16:1(9Z)/17:0cycw7c) CL(17:0cycw7c/16:0/16:1(9Z)/17:0cycw7c) is a cardiolipin (CL). Cardiolipins are sometimes called a 'double' phospholipid because they have four fatty acid tails, instead of the usual two. CL(17:0cycw7c/16:0/16:1(9Z)/17:0cycw7c) contains two chains of (heptadec-9-10-cyclo-anoyl) at the C1 and C4 positions, one chain of hexadecanoic acid at the C2 position, one chain of (9Z-hexadecenoyl) at the C3 position. 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. 1'-[1-heptadec-9-10-cyclo-anoyl-2-hexadecanoyl-sn-glycero-3-phospho],3'-[1,2-di(9Z-hexadecenoyl)-rac-glycero-3-phospho]-glycerol 1'-[1-heptadec-9-10-cyclo-anoyl-2-palmitoyl-sn-glycero-3-phospho],3'-[1,2-dipalmitoleoyl-rac-glycero-3-phospho]-glycerol Cardiolipin(17:0/16:0/16:1/16:1) Cardiolipin(65:2) CL(1'-[17:0cycw7c/16:0],3'-[16:1(9Z)/16:1(9Z)]) CL(17:0/16:0/16:1/16:1) CL(65:2) C75H140O17P2 1375.876 1374.956577044 [(2S)-3-({[(2R)-3-[(9Z)-hexadec-9-enoyloxy]-2-{[8-(2-hexylcyclopropyl)octanoyl]oxy}propoxy](hydroxy)phosphoryl}oxy)-2-hydroxypropoxy][(2R)-2-(hexadecanoyloxy)-3-{[8-(2-hexylcyclopropyl)octanoyl]oxy}propoxy]phosphinic acid (2S)-3-{[(2R)-3-[(9Z)-hexadec-9-enoyloxy]-2-{[8-(2-hexylcyclopropyl)octanoyl]oxy}propoxy(hydroxy)phosphoryl]oxy}-2-hydroxypropoxy((2R)-2-(hexadecanoyloxy)-3-{[8-(2-hexylcyclopropyl)octanoyl]oxy}propoxy)phosphinic acid [H][C@](O)(COP(O)(=O)OC[C@@]([H])(COC(=O)CCCCCCCC1CC1CCCCCC)OC(=O)CCCCCCCCCCCCCCC)COP(O)(=O)OC[C@@]([H])(COC(=O)CCCCCCC\C=C/CCCCCC)OC(=O)CCCCCCCC1CC1CCCCCC InChI=1S/C75H140O17P2/c1-5-9-13-17-19-21-23-25-27-29-31-37-45-53-72(77)85-61-71(92-75(80)56-48-40-34-36-44-52-68-58-66(68)50-42-16-12-8-4)64-90-94(83,84)88-60-69(76)59-87-93(81,82)89-63-70(91-74(79)55-47-38-32-30-28-26-24-22-20-18-14-10-6-2)62-86-73(78)54-46-39-33-35-43-51-67-57-65(67)49-41-15-11-7-3/h21,23,65-71,76H,5-20,22,24-64H2,1-4H3,(H,81,82)(H,83,84)/b23-21-/t65?,66?,67?,68?,69-,70+,71+/m0/s1 OUFVODKNKCOKFR-FELJNGSLSA-N Solid Membrane logp 8.88 ALOGPS logs -7.49 ALOGPS solubility 4.46e-05 g/l ALOGPS logp 22.68 ChemAxon pka_strongest_acidic 1.59 ChemAxon pka_strongest_basic -3.4 ChemAxon iupac [(2S)-3-({[(2R)-3-[(9Z)-hexadec-9-enoyloxy]-2-{[8-(2-hexylcyclopropyl)octanoyl]oxy}propoxy](hydroxy)phosphoryl}oxy)-2-hydroxypropoxy][(2R)-2-(hexadecanoyloxy)-3-{[8-(2-hexylcyclopropyl)octanoyl]oxy}propoxy]phosphinic acid ChemAxon average_mass 1375.876 ChemAxon mono_mass 1374.956577044 ChemAxon smiles [H][C@](O)(COP(O)(=O)OC[C@@]([H])(COC(=O)CCCCCCCC1CC1CCCCCC)OC(=O)CCCCCCCCCCCCCCC)COP(O)(=O)OC[C@@]([H])(COC(=O)CCCCCCC\C=C/CCCCCC)OC(=O)CCCCCCCC1CC1CCCCCC ChemAxon formula C75H140O17P2 ChemAxon inchi InChI=1S/C75H140O17P2/c1-5-9-13-17-19-21-23-25-27-29-31-37-45-53-72(77)85-61-71(92-75(80)56-48-40-34-36-44-52-68-58-66(68)50-42-16-12-8-4)64-90-94(83,84)88-60-69(76)59-87-93(81,82)89-63-70(91-74(79)55-47-38-32-30-28-26-24-22-20-18-14-10-6-2)62-86-73(78)54-46-39-33-35-43-51-67-57-65(67)49-41-15-11-7-3/h21,23,65-71,76H,5-20,22,24-64H2,1-4H3,(H,81,82)(H,83,84)/b23-21-/t65?,66?,67?,68?,69-,70+,71+/m0/s1 ChemAxon inchikey OUFVODKNKCOKFR-FELJNGSLSA-N ChemAxon polar_surface_area 236.95 ChemAxon refractivity 376.61 ChemAxon polarizability 164.41 ChemAxon rotatable_bond_count 75 ChemAxon acceptor_count 9 ChemAxon donor_count 3 ChemAxon physiological_charge -2 ChemAxon formal_charge 0 ChemAxon Glycerophospholipid metabolism ec00564 phospholipid biosynthesis CL(17:0cycw7c/16:0/16:1(9Z)/17:0cycw7c) "Phospholipids are membrane components in E. coli. 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."
