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(19:0cycv8c/16:1(9Z)), in particular, consists of one heptadec-11-12-cyclo-anoyl chain to the C-1 atom, and one 9Z-hexadecenoyl 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.C41H77O10P761.031760.525435677[(2S)-2,3-dihydroxypropoxy][(2R)-3-[(9Z)-hexadec-9-enoyloxy]-2-{[10-(2-hexylcyclopropyl)decanoyl]oxy}propoxy]phosphinic acid(2S)-2,3-dihydroxypropoxy((2R)-3-[(9Z)-hexadec-9-enoyloxy]-2-{[10-(2-hexylcyclopropyl)decanoyl]oxy}propoxy)phosphinic acid[H][C@](O)(CO)COP(O)(=O)OC[C@@]([H])(COC(=O)CCCCCCC\C=C/CCCCCC)OC(=O)CCCCCCCCCC1CC1CCCCCCInChI=1S/C41H77O10P/c1-3-5-7-9-10-11-12-13-14-15-18-21-25-29-40(44)48-34-39(35-50-52(46,47)49-33-38(43)32-42)51-41(45)30-26-22-19-16-17-20-24-28-37-31-36(37)27-23-8-6-4-2/h11-12,36-39,42-43H,3-10,13-35H2,1-2H3,(H,46,47)/b12-11-/t36?,37?,38-,39+/m0/s1YLJXEPYAINITBA-OWIVCOGVSA-Nlogp7.98logs-6.85solubility1.07e-04 g/llogp11.13pka_strongest_acidic1.89pka_strongest_basic-3iupac[(2S)-2,3-dihydroxypropoxy][(2R)-3-[(9Z)-hexadec-9-enoyloxy]-2-{[10-(2-hexylcyclopropyl)decanoyl]oxy}propoxy]phosphinic acidaverage_mass761.031mono_mass760.525435677smiles[H][C@](O)(CO)COP(O)(=O)OC[C@@]([H])(COC(=O)CCCCCCC\C=C/CCCCCC)OC(=O)CCCCCCCCCC1CC1CCCCCCformulaC41H77O10PinchiInChI=1S/C41H77O10P/c1-3-5-7-9-10-11-12-13-14-15-18-21-25-29-40(44)48-34-39(35-50-52(46,47)49-33-38(43)32-42)51-41(45)30-26-22-19-16-17-20-24-28-37-31-36(37)27-23-8-6-4-2/h11-12,36-39,42-43H,3-10,13-35H2,1-2H3,(H,46,47)/b12-11-/t36?,37?,38-,39+/m0/s1inchikeyYLJXEPYAINITBA-OWIVCOGVSA-Npolar_surface_area148.82refractivity208.32polarizability90.98rotatable_bond_count40acceptor_count6donor_count3physiological_charge-1formal_charge0phospholipid biosynthesis (CL(19:0cycv8c/16:1(9Z)/17:0cycw7c/16:1(9Z)))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.PW001384Metabolicphospholipid biosynthesis (CL(19:0cycv8c/16:1(9Z)/17:0cycw7c/19:0cycv8c))Phospholipids are membrane components in E. coli.
