Description
  • The phosphatidylglycerol deficient Delta pgsA mutant of Synechocystis PCC6803 provided a unique experimental system for investigating in vivo retailoring of exogenously added dioleoylphosphatidylglycerol, in phosphatidylglycerol-depleted cells. Gas chromatographic analysis of fatty acid composition suggested that diacyl-phosphatidylglycerols were synthesized from the artificial synthetic precursor. The formation of new. retailored lipid species was confirmed by negative-ion electrospray ionization-Fourier-transform ion cyclotron resonance and ion trap tandem mass spectrometry. Various isomeric diacyl-phosphatidylglycerols were identified indicating transesterification of the exogenously added dioleoylphosphatidyl-glycerol at the sn-1 or sn-2 positions. Polyunsaturated fatty acids were incorporated selectively into the sn-1 position. Our experiments with Synechocystis PCC6803/Delta pgsA mutant cells demonstrated lipid remodeling in a prokaryotic photosynthetic bacterium.
