Cloning and nucleotide sequence of opdA, the gene encoding oligopeptidase A in Salmonella typhimurium.
The opdA gene (formerly called optA) of Salmonella typhimurium encodes a metallopeptidase, oligopeptidase A (OpdA), first recognized by its ability to cleave and allow utilization of N-acetyl-L-Ala4 (E. R. Vimr, L. Green, and C. G. Miller, J. Bacteriol. 153:1259-1265, 1983). Derivatives of pBR328 carrying the opdA gene were isolated and shown to express oligopeptidase activity at levels approxi...
متن کاملNucleotide sequence of the Salmonella typhimurium himA gene.
The DNA sequence of the Salmonella typhimurium glyA gene has been determined. The polypeptide deduced from the DNA sequence contains 417 amino acids and has a calculated molecular weight of 45428 daltons. S1 nuclease mapping experiments located the transcription start point and possible transcription termination region. The nucleotide and amino acid sequences for the S. typhimurium and Escheric...
متن کاملStep Cloning of Salmonella typhimurium Gene Fusions
Transcriptional fusions to Salmonella typhimurium chromosomal genes were constructed by integration of a suicide fusion vector into the chromosome by homologous recombination with random cloned chromosomal fragments. We describe here a transductional method using the generalized transducing phage of S. typhimurium, P22, to clone these fusions directly from the bacterial chromosome, in a single ...
متن کاملThe Salmonella typhimurium katF (rpoS) gene: cloning, nucleotide sequence, and regulation of spvR and spvABCD virulence plasmid genes.
The spv region of Salmonella virulence plasmids is essential for the development of a systemic infection in mice. Transcriptional activation of the spvABCD operon occurs during stationary growth phase and is mediated by the regulatory gene product SpvR. We have previously shown that expression of a spvRAB'-cat fusion in Escherichia coli was dependent on the katF (rpoS) locus which encodes an al...
متن کاملCloning and nucleotide sequence of the cyclic AMP receptor protein-regulated Salmonella typhimurium pepE gene and crystallization of its product, an alpha-aspartyl dipeptidase.
The Salmonella typhimurium pepE gene, encoding an N-terminal-Asp-specific dipeptidase, has been cloned on pBR328 by complementation of the Asp-Pro growth defect conferred by a pepE mutation. Strains carrying the complementing plasmids greatly overproduce peptidase E. The enzyme has been purified from an extract of such a strain, its N-terminal amino acid sequence has been determined, and crysta...
