title: The Staphylococcus carnosus secE gene: cloning, nucleotide sequence, and functional characterization in Escherichia coli secE mutant strains.
abstract: A DNA fragment containing the genes secE, nusG and rplK of Staphylococcus carnsosus was cloned using the Escherichia coli rplK gene as a probe. The S. carnosus secE homologue encodes a protein of 65 amino acid residues which is homologous to the carboxyl-terminal region of the E. coli SecE protein. The S. carnosus SecE polypeptide which, in contrast to the E. coli SecE protein, contains only one putative transmembrane segment, could fully replace the E. coli SecE protein in two different secE mutants. These results strongly suggest that the identified secE gene encodes an important component of the S. carnosus protein export apparatus.
