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(18:1(11Z)/17:0), in particular, consists of one 11Z-octadecenoyl chain to the C-1 atom, and one heptadecanoyl 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-(11Z-octadecenoyl)-2-margaroyl-sn-glycero-3-phospho-(1'-glycerol)1-(11Z-octadecenoyl)-2-margaroyl-sn-glycero-3-phosphoglycerol1-vaccenoyl-2-heptadecanoyl-sn-glycero-3-phosphoglycerolGPG(18:1/17:0)GPG(35:1)PG(18:1/17:0)PG(35:1)Phosphatidylglycerol(18:1/17:0)Phosphatidylglycerol(35:1)C41H79O10P763.0337762.54108526[(2S)-2,3-dihydroxypropoxy][(2R)-3-(heptadecanoyloxy)-2-[(11Z)-octadec-11-enoyloxy]propoxy]phosphinic acid(2S)-2,3-dihydroxypropoxy(2R)-3-(heptadecanoyloxy)-2-[(11Z)-octadec-11-enoyloxy]propoxyphosphinic acid[H]\C(CCCCCC)=C(/[H])CCCCCCCCCC(=O)O[C@]([H])(COC(=O)CCCCCCCCCCCCCCCC)COP(O)(=O)OC[C@@]([H])(O)COInChI=1S/C41H79O10P/c1-3-5-7-9-11-13-15-17-19-21-23-25-27-29-31-33-41(45)51-39(37-50-52(46,47)49-35-38(43)34-42)36-48-40(44)32-30-28-26-24-22-20-18-16-14-12-10-8-6-4-2/h13,15,38-39,42-43H,3-12,14,16-37H2,1-2H3,(H,46,47)/b15-13-/t38-,39+/m0/s1LTIMJOQJSBVVQU-LFZSHSSHSA-NInner membraneMembraneOuter membranelogp8.37logs-6.94solubility8.76e-05 g/llogp11.91pka_strongest_acidic1.89pka_strongest_basic-3iupac[(2S)-2,3-dihydroxypropoxy][(2R)-3-(heptadecanoyloxy)-2-[(11Z)-octadec-11-enoyloxy]propoxy]phosphinic acidaverage_mass763.0337mono_mass762.54108526smiles[H]\C(CCCCCC)=C(/[H])CCCCCCCCCC(=O)O[C@]([H])(COC(=O)CCCCCCCCCCCCCCCC)COP(O)(=O)OC[C@@]([H])(O)COformulaC41H79O10PinchiInChI=1S/C41H79O10P/c1-3-5-7-9-11-13-15-17-19-21-23-25-27-29-31-33-41(45)51-39(37-50-52(46,47)49-35-38(43)34-42)36-48-40(44)32-30-28-26-24-22-20-18-16-14-12-10-8-6-4-2/h13,15,38-39,42-43H,3-12,14,16-37H2,1-2H3,(H,46,47)/b15-13-/t38-,39+/m0/s1inchikeyLTIMJOQJSBVVQU-LFZSHSSHSA-Npolar_surface_area148.82refractivity210.23polarizability92.09rotatable_bond_count42acceptor_count6donor_count3physiological_charge-1formal_charge0Glycerophospholipid metabolismec00564phospholipid biosynthesis (CL(18:1(9Z)/15:0cyclo/17:0cycw7c/15:0cyclo))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.PW001527Metabolicphospholipid biosynthesis (CL(18:1(9Z)/17:0cycw7c/17:0cycw7c/17:0cycw7c))Phospholipids are membrane components in E. coli.
