Sažetak
The role of nucleotide excision repair in the mutagenicity of the monofunctional alkylating agents N-methyl-N'-nitro-N-nitrosoguanidine (MNNG), methyl methanesulfonate (MMS), N-ethyl-N'-nitro-N-nitrosoguanidine (ENNG), and N-ethyl-N-nitrosourea (ENU) in Salmonella typhimurium was examined. The mutagenic potential of the mutagenic agents used increased in the following order: MMS less than ENU less than ENNG less than MNNG. The results obtained confirm the involvement of nucleotide excision repair in the removal of mutagenic lesions from the DNA of S. typhimurium cells exposed to high doses of methylating as well as ethylating agents. At the low doses of all the alkylating agents used, the nucleotide excision repair-proficient strain was mutagenized more efficiently than the uvrB mutant. This phenomenon, a consequence of competition between nucleotide excision-repair enzymes and constitutive O6-methylguanine-DNA methyltransferase, is discussed.
