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(12:0(3-OH)/17:0cycw7c), in particular, consists of one 3-hydroxydodecanoyl 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-hydroxydodecanoyl-2-heptadec-9-10-cyclo-anoyl-sn-glycero-3-phospho-(1'-glycerol)1-3-hydroxydodecanoyl-2-heptadec-9-10-cyclo-anoyl-sn-glycero-3-phosphoglycerol1-3-hydroxydodecanoyl-2-heptadec-9-10-cyclo-anoyl-sn-glycero-3-phosphoglycerolGPG(12:0/17:0)GPG(29:0)PG(12:0/17:0)PG(29:0)Phosphatidylglycerol(12:0/17:0)Phosphatidylglycerol(29:0)C35H67O11P694.884694.442099975[(2S)-2,3-dihydroxypropoxy][(2R)-3-{[8-(2-hexylcyclopropyl)octanoyl]oxy}-2-[(3-hydroxydodecanoyl)oxy]propoxy]phosphinic acid(2S)-2,3-dihydroxypropoxy((2R)-3-{[8-(2-hexylcyclopropyl)octanoyl]oxy}-2-[(3-hydroxydodecanoyl)oxy]propoxy)phosphinic acid[H][C@](O)(CO)COP(O)(=O)OC[C@@]([H])(COC(=O)CCCCCCCC1CC1CCCCCC)OC(=O)CC(O)CCCCCCCCCInChI=1S/C35H67O11P/c1-3-5-7-9-10-13-17-21-31(37)24-35(40)46-33(28-45-47(41,42)44-26-32(38)25-36)27-43-34(39)22-18-14-11-12-16-20-30-23-29(30)19-15-8-6-4-2/h29-33,36-38H,3-28H2,1-2H3,(H,41,42)/t29?,30?,31?,32-,33+/m0/s1YVRUTOLLRQUDBY-QOGUGHGESA-NSolidMembranelogp5.67logs-6.12solubility5.28e-04 g/llogp7.59pka_strongest_acidic1.89pka_strongest_basic-2.8iupac[(2S)-2,3-dihydroxypropoxy][(2R)-3-{[8-(2-hexylcyclopropyl)octanoyl]oxy}-2-[(3-hydroxydodecanoyl)oxy]propoxy]phosphinic acidaverage_mass694.884mono_mass694.442099975smiles[H][C@](O)(CO)COP(O)(=O)OC[C@@]([H])(COC(=O)CCCCCCCC1CC1CCCCCC)OC(=O)CC(O)CCCCCCCCCformulaC35H67O11PinchiInChI=1S/C35H67O11P/c1-3-5-7-9-10-13-17-21-31(37)24-35(40)46-33(28-45-47(41,42)44-26-32(38)25-36)27-43-34(39)22-18-14-11-12-16-20-30-23-29(30)19-15-8-6-4-2/h29-33,36-38H,3-28H2,1-2H3,(H,41,42)/t29?,30?,31?,32-,33+/m0/s1inchikeyYVRUTOLLRQUDBY-QOGUGHGESA-Npolar_surface_area169.05refractivity181.11polarizability80.08rotatable_bond_count35acceptor_count7donor_count4physiological_charge-1formal_charge0Glycerophospholipid metabolismec00564phospholipid biosynthesis (CL(12:0(3-OH)/17:0cycw7c/12:0(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.
