Abstract excerpt
Strains of Escherichia coli carrying mutations at the relA locus are deficient in cyclopropane fatty acid (CFA) synthesis, a phospholipid modification that occurs as cultures enter stationary phase. RelA protein catalyzes the synthesis of guanosine-3',5'-bisdiphosphate (ppGpp); therefore, ppGpp w...
