pubmed:abstractText |
Mutagenesis was demonstrable after delayed photoreversal of UV-irradiated strains carrying a recA deletion indicating that RecA protein is not essential for the misincorporation process that is revealed by delayed photoreversal. Moreover, the data suggest that RecA protein actually depresses misincorporation to varying extents depending on the recA allele. No delayed photoreversal was demonstrable in reA1 or recA56 bacteria unless the lexA102(ind-) allele was also present. It is suggested that the level of these RecA proteins may be lower in the lexA102(ind-) strains thus minimising their depressive effect. Delayed photoreversal mutagenesis in strains carrying the recA441 allele was not affected by either adenine or guanosine plus cytidine, substances which affect the proteolytic activity of RecA441 protein.
