Abstract:
| The Escherichia coli RecR protein participates in a recombinational DNA repair process. Its gene is located in a region of chromosome that extends from 502 to 509 kilobases on the physical map and that contains apt, dnaX, orf12-recR, htpG, and adk. Most, if not all, of these are involved in nucleic acid metabolism. The orf12-recR reading frames consist of 935 base pairs and overlap by one nucleotide, with the 3' A of the orf12 termination codon forming the 5' nucleotide of the recR initiation codon. The orf12-recR promoter was located upstream of orf12 by sequence analysis, promoter cloning, and S1 nuclease protection analysis. The start point of transcription was determined by primer extension. The transcript 5' end contained a long, apparently untranslated region of 199 nucleotides. Absence of a detectable promoter specific for recR and the overlap of the orf12 and recR reading frames suggest that translation of recR is coupled to that of orf12. By maxicell analysis, it was determined that both orf12 and recR are translated. |
