Abstract

Treatment of with diazaborine strongly induces the synthesis of a 28 kDa protein which is associated with the cytoplasmic membrane. The partial amino acid sequence proved that this protein is identical to the phage shock protein PspA. The kinetics of the expression of the gene were determined in an strain which carried a fusion in the chromosome. PspA synthesis is independent of the growth phase. It is, however, strongly induced when fatty acid biosynthesis is inhibited by diazaborine or cerulenin. Treatment with either compound also causes dose-dependent inhibition of phospholipid biosynthesis whose degree correlates with the induction of PspA. Another cause of induction of PspA synthesis is treatment of with globomycin, which is an inhibitor of the processing of lipoproteins.
