RESUMO

A pBR322 plasmid which contains a fragment of Escherichia coli DNA encoding the lipoprotein signal peptidase gene was used to transform Hfr polA1 strains. Ampr transformants were used as donors in conjugation experiments, and the location of the plasmid amp gene adjacent to the chromosomal lsp gene was determined to be near the thr ara loci of the E. coli chromosome. P1 transduction experiments established that the location of the lsp gene is closely linked to that of dapB , at 0.5 to 0.6 min on the E. coli genetic map. The position of the lsp gene was further determined to be between ileS and dapB by complementation analysis of an E. coli mutant showing temperature-sensitive prolipoprotein signal peptidase activity.
