Abstract:
| A gene is identified in the Escherichia coli K-12 spo operon as recG. Previously identified genes in the spo operon were spoS, alias rpoZ, encoding the omega (omega) subunit of RNA polymerase, as well as the spoT gene encoding the major cellular source of guanosine 3',5'-bispyrophosphate hydrolase activity. The gene order within the spo operon is: spoS (rpoZ), spoT, spoU, recG. A convergent gltS gene is present beyond the spo operon. Mutants bearing recG deletion-insertion alleles display mild sensitivities to both ultraviolet irradiation and to mitomycin C, which is expected to be due to a known recG insertion allele. Deletion-insertion mutations in upstream operon genes (spoT and spoU) show polar effects on these assays of recG function. The deduced 693-amino acid (aa) RecG sequence shows a weak, but significant, relatedness to aa sequence motifs previously reported for putative helicases involved in replication, recombination, and DNA repair. |
