Opis:: The SOS system and SOS mutagenesis are frequently studied, or exploited to obtain an increase in mutagenicity of bacteria. Here a short survey is made of the phenomenon of SOS response with special attention to latest and less discussed data, especially the induction of the SOS system in response to cell starvation or mutation of certain genes and the role of inducible DNA polymerases.

Opis:: The mutagenicity of two, newly synthesized amino-derivatives of cyclopenta[c]phenanthrene (CP[c]Ph) was investigated in the Ames test using TA98 and TA100 histidine dependent Salmonella typhimurium strains. Neither of the examined compounds showed mutagenic activity without metabolic activation. The incorporation of an activation system caused high mutagenicity of CP[c]Ph derivatives in both S. typhimurium strains. The results are compared with the previous data on the mutagenic activity of unsubstituted CP[c]Ph and possible mechanisms of activation are discussed.

Tytuł:: A new look at adaptive mutations in bacteria.
Autorzy:: Janion, Celina
Powiązania:: https://bibliotekanauki.pl/articles/1044374.pdf
Data publikacji:: 2000
Wydawca:: Polskie Towarzystwo Biochemiczne
Tematy:: adaptive mutations
DNA damage
DNA repair
Opis:: This is a short survey of the adaptive mutation processes that arise in non- or slowly- dividing bacterial cells and includes: (i) bacterial models in which adaptive mutations are studied; (ii) the mutagenic lesions from which these mutations derive; (iii) the influence of DNA repair processes on the spectrum of adaptive mutations. It is proposed that in starved cells, likely as during the MFD phenomenon, lesions in tRNA suppressor genes are preferentially repaired and no suppressor tRNAs are formed as a result of adaptive mutations. Perhaps the most provocative proposal is (iv) a hypothesis that the majority of adaptive mutations are selected in a pre-apoptotic state where the cells are either mutated, selected, and survive, or they die.
