Abstract

We identified proteins whose amounts were altered in an Escherichia coli pgsA3 mutant lacking the potential to synthesize phosphatidylglycerolphosphate, a precursor of phosphatidylglycerol. Proteins whose amounts were increased in the mutant were protease Do, periplasmic oligopeptide-binding protein, tryptophanase, and an unidentified protein, while the decreased one was flagellin. Transformation of the mutant with a plasmid containing the wild type pgsA gene complemented the phenotype, indicating that the pgsA3 mutation is responsible for the phenotype.
