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(14:0(3-OH)/17:0cycw7c), in particular, consists of one 3-hydroxytetradecanoyl chain to the C-1 atom, and one heptadec-9-10-cyclo-anoyl 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-hydroxytetradecanoyl-2-heptadec-9-10-cyclo-anoyl-sn-glycero-3-phospho-(1'-glycerol)1-3-hydroxytetradecanoyl-2-heptadec-9-10-cyclo-anoyl-sn-glycero-3-phosphoglycerol1-3-hydroxytetradecanoyl-2-heptadec-9-10-cyclo-anoyl-sn-glycero-3-phosphoglycerolGPG(14:0/17:0)GPG(31:0)PG(14:0/17:0)PG(31:0)Phosphatidylglycerol(14:0/17:0)Phosphatidylglycerol(31:0)C37H71O11P722.938722.473400104[(2S)-2,3-dihydroxypropoxy][(2R)-3-{[8-(2-hexylcyclopropyl)octanoyl]oxy}-2-[(3-hydroxytetradecanoyl)oxy]propoxy]phosphinic acid(2S)-2,3-dihydroxypropoxy((2R)-3-{[8-(2-hexylcyclopropyl)octanoyl]oxy}-2-[(3-hydroxytetradecanoyl)oxy]propoxy)phosphinic acid[H][C@](O)(CO)COP(O)(=O)OC[C@@]([H])(COC(=O)CCCCCCCC1CC1CCCCCC)OC(=O)CC(O)CCCCCCCCCCCInChI=1S/C37H71O11P/c1-3-5-7-9-10-11-12-15-19-23-33(39)26-37(42)48-35(30-47-49(43,44)46-28-34(40)27-38)29-45-36(41)24-20-16-13-14-18-22-32-25-31(32)21-17-8-6-4-2/h31-35,38-40H,3-30H2,1-2H3,(H,43,44)/t31?,32?,33?,34-,35+/m0/s1NCFDTLKDDWOMGW-BISNVOBLSA-NSolidMembranelogp6.27logs-6.33solubility3.41e-04 g/llogp8.48pka_strongest_acidic1.89pka_strongest_basic-2.8iupac[(2S)-2,3-dihydroxypropoxy][(2R)-3-{[8-(2-hexylcyclopropyl)octanoyl]oxy}-2-[(3-hydroxytetradecanoyl)oxy]propoxy]phosphinic acidaverage_mass722.938mono_mass722.473400104smiles[H][C@](O)(CO)COP(O)(=O)OC[C@@]([H])(COC(=O)CCCCCCCC1CC1CCCCCC)OC(=O)CC(O)CCCCCCCCCCCformulaC37H71O11PinchiInChI=1S/C37H71O11P/c1-3-5-7-9-10-11-12-15-19-23-33(39)26-37(42)48-35(30-47-49(43,44)46-28-34(40)27-38)29-45-36(41)24-20-16-13-14-18-22-32-25-31(32)21-17-8-6-4-2/h31-35,38-40H,3-30H2,1-2H3,(H,43,44)/t31?,32?,33?,34-,35+/m0/s1inchikeyNCFDTLKDDWOMGW-BISNVOBLSA-Npolar_surface_area169.05refractivity190.32polarizability84.71rotatable_bond_count37acceptor_count7donor_count4physiological_charge-1formal_charge0Glycerophospholipid metabolismec00564phospholipid biosynthesis (CL(14:0(3-OH)/17:0cycw7c/14:0(3-OH)/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.PW001941Metabolicphospholipid biosynthesis (CL(14:0(3-OH)/17:0cycw7c/14:0/14:0))Phospholipids are membrane components in E. coli.
