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 کاملNucleotide sequence and biochemical characterization of the metJ gene from Salmonella typhimurium LT2.
The nucleotide sequence of the Salmonella typhimurium metJ gene is presented along with the sequence of the promoter region for the closely linked metB gene. The two genes are transcribed in opposite directions, with transcription initiating from a single promoter for metB, and from two apparent promoters for metJ. RNA polymerase binding sites for metJ and metB, determined by in vitro protectio...
متن کاملMultilocus Sequence Typing of the Clinical Isolates of Salmonella Enterica Serovar Typhimurium in Tehran Hospitals
Background: Salmonella enterica serovar Typhimurium is one of the most important serovars of Salmonella enterica and is associated with human salmonellosis worldwide. Many epidemiological studies have focused on the characteristics of Salmonella Typhimurium in many countries as well as in Asia. This study was conducted to investigate the genetic characteristics of Salmonella Typhimurium using m...
متن کاملCOMPARATIVE CHARACTERIZATION OF PORINS FROM SALMONELLA TYPHIO-901 AND SALMONELLA TYPHIMURIUM RA-30
Porins from Salmonella typhi 0-901 and Salmonella typhimurium Ra-30 were characterized and compared. The elution profile of porins from these salmonella species on Sepharose-48 and HPLC appear to be very similar. The findings were confirmed by the electrophoretic pattern which showed three types of porins, i.e. OmpC, OmpD and OmpF in both species. These porins appear to be similar, if not ...
