Phosphatidylglycerols consist of a glycerol 3-phosphate backbone esterified to either saturated or unsaturated fatty acids on carbons 1 and 2. As is the case with diacylglycerols, phosphatidylglycerols can have many different combinations of fatty acids of varying lengths and saturation attached to the C-1 and C-2 positions. PG(10:0(3-OH)/18:1(9Z)), in particular, consists of one 3-hydroxydecanoyl chain to the C-1 atom, and one 9Z-octadecenoyl to the C-2 atom. In E. coli glycerophospholipid metabolism, phosphatidylglycerol is formed from phosphatidic acid (1,2-diacyl-sn-glycerol 3-phosphate) by a sequence of enzymatic reactions that proceeds via two intermediates, cytidine diphosphate diacylglycerol (CDP-diacylglycerol) and phosphatidylglycerophosphate (PGP, a phosphorylated phosphatidylglycerol). Phosphatidylglycerols, along with CDP-diacylglycerol, also serve as precursor molecules for the synthesis of cardiolipin, a phospholipid found in membranes.1-3-hydroxydecanoyl-2-(9Z-octadecenoyl)-sn-glycero-3-phospho-(1'-glycerol)1-3-hydroxydecanoyl-2-(9Z-octadecenoyl)-sn-glycero-3-phosphoglycerol1-3-hydroxydecanoyl-2-oleoyl-sn-glycero-3-phosphoglycerol1-NULL-2-(9Z-octadecenoyl)-sn-glycero-3-phospho-(1'-glycerol)1-NULL-2-(9Z-octadecenoyl)-sn-glycero-3-phosphoglycerolGPG(10:0/18:1)GPG(28:1)PG(10:0/18:1)PG(28:1)Phosphatidylglycerol(10:0/18:1)Phosphatidylglycerol(28:1)C34H65O11P680.857680.426449911[(2S)-2,3-dihydroxypropoxy][(2R)-2-[(3-hydroxydecanoyl)oxy]-3-[(9Z)-octadec-9-enoyloxy]propoxy]phosphinic acid(2S)-2,3-dihydroxypropoxy((2R)-2-[(3-hydroxydecanoyl)oxy]-3-[(9Z)-octadec-9-enoyloxy]propoxy)phosphinic acid[H][C@](O)(CO)COP(O)(=O)OC[C@@]([H])(COC(=O)CCCCCCC\C=C/CCCCCCCC)OC(=O)CC(O)CCCCCCCInChI=1S/C34H65O11P/c1-3-5-7-9-10-11-12-13-14-15-16-17-18-20-22-24-33(38)42-28-32(29-44-46(40,41)43-27-31(37)26-35)45-34(39)25-30(36)23-21-19-8-6-4-2/h13-14,30-32,35-37H,3-12,15-29H2,1-2H3,(H,40,41)/b14-13-/t30?,31-,32+/m0/s1GLNVNEGENVXBJX-HJVFSXHRSA-NSolidMembranelogp5.79logs-6.06solubility5.92e-04 g/llogp7.57pka_strongest_acidic1.89pka_strongest_basic-2.8iupac[(2S)-2,3-dihydroxypropoxy][(2R)-2-[(3-hydroxydecanoyl)oxy]-3-[(9Z)-octadec-9-enoyloxy]propoxy]phosphinic acidaverage_mass680.857mono_mass680.426449911smiles[H][C@](O)(CO)COP(O)(=O)OC[C@@]([H])(COC(=O)CCCCCCC\C=C/CCCCCCCC)OC(=O)CC(O)CCCCCCCformulaC34H65O11PinchiInChI=1S/C34H65O11P/c1-3-5-7-9-10-11-12-13-14-15-16-17-18-20-22-24-33(38)42-28-32(29-44-46(40,41)43-27-31(37)26-35)45-34(39)25-30(36)23-21-19-8-6-4-2/h13-14,30-32,35-37H,3-12,15-29H2,1-2H3,(H,40,41)/b14-13-/t30?,31-,32+/m0/s1inchikeyGLNVNEGENVXBJX-HJVFSXHRSA-Npolar_surface_area169.05refractivity179.54polarizability78.57rotatable_bond_count35acceptor_count7donor_count4physiological_charge-1formal_charge0Glycerophospholipid metabolismec00564phospholipid biosynthesis (CL(18:1(11Z)/10:0/10:0/10:0))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.
