Abstract
In the nuclear compartment of yeast, NuB4 core complex consists of three proteins, Hat1, Hat2, and Hif1, and interacts with a number of other factors. In particular, it was shown that NuB4 complex physically interacts with Hsm3p. Early we demonstrated that the gene HSM3 participates in the control of replicative and reparative spontaneous mutagenesis, and that hsm3Δ mutants increase the frequency of mutations induced by different mutagens. It was previously believed that the HSM3 gene controlled only some minor repair processes in the cell, but later it was suggested that it had a chaperone function with its participation in proteasome assembly. In this work, we analyzed the properties of three hsm3Δ, hif1Δ, and hat1Δ mutants. The results obtained showed that the Hsm3 protein may be a functional subunit of NuB4 complex. It has been shown that hsm3- and hif1-dependent UV-induced mutagenesis is completely suppressed by inactivation of the Polη polymerase. We showed a significant role of Polη for hsm3-dependent mutagenesis at non-bipyrimidine sites (NBP sites). The efficiency of expression of RNR (RiboNucleotid Reducase) genes after UV irradiation in hsm3Δ and hif1Δ mutants was several times lower than in wild-type cells. Thus, we have presented evidence that significant increase in the dNTP levels suppress hsm3- and hif1-dependent mutagenesis and Polη is responsible for hsm3- and hif1-dependent mutagenesis.

Abstract
In eukaryotes, DNA damage tolerance (DDT) is determined by two repair pathways, homologous repair recombination (HRR) and a pathway controlled by the RAD6-epistatic group of genes. Monoubiquitylation of PCNA mediates an error-prone pathway, whereas polyubiquitylation stimulates an error-free pathway. The error-free pathway involves components of recombination repair; however, the factors that act in this pathway remain largely unknown. Here, we report that the HIM1 gene participates in error-free DDT. Notably, inactivation RAD30 gene encoding Polη completely suppresses him1-dependent UV mutagenesis. Furthermore, data obtained show a significant role of Polη in him1-dependent mutagenesis, especially at non-bipyrimidine sites (NBP sites). We demonstrate that him1 mutation significantly reduces the efficiency of the induction expression of RNR genes after UV irradiation. Besides, this paper presents evidence that significant increase in the dNTP levels suppress him1-dependent mutagenesis. Our findings show that Polη responsible for him1-dependent mutagenesis.

Abstract
We have previously reported about a new Saccharomyces cerevisiae mutation, hsm2-1, that results in increase of both spontaneous and UV-induced mutation frequencies but does not alter UV-sensitivity. Now HSM2 gene has been genetically and physically mapped and identified as a gene previously characterized as HMO1, a yeast homologue of human high mobility group genes HMG1/2. We found that hsm2 mutant is slightly deficient in plasmid-borne mismatch repair. We tested UV-induced mutagenesis in double mutants carrying hsm2-1 mutation and a mutation in a gene of principal damaged DNA repair pathways (rad2 and rev3) or in a mismatch repair gene (pms1 and recently characterized in our laboratory hsm3). The frequency of UV-induced mutations in hsm2 rev3 was not altered in comparison with single rev3 mutant. In contrast, the interaction of hsm2-1 with rad2 and pms1 was characterized by an increased frequency of UV-induced mutations in comparison with single rad2 and pms1 mutants. The UV-induced mutation frequency in double hsm2 hsm3 mutant was lower than in the single hsm2 and hsm3 mutants. The role of the HSM2 gene product in control of mutagenesis is discussed.

Abstract
Mutants with enhanced spontaneous mutability (hsm) to canavanine resistance were induced by N-methyl-N-nitrosourea in Saccharomyces cerevisiae. One bearing the hsm3-1 mutation was used for this study. This mutation does not increase sensitivity to the lethal action of different mutagens. The hsm3-1 mutation produces a mutator phenotype, enhancing the rates of spontaneous mutation to canavanine resistance and reversions of lys1-1 and his1-7. This mutation increases the rate of intragenic mitotic recombination at the ADE2 gene. The ability of the hsm3 mutant to correct DNA heteroduplex is reduced in comparison with the wild-type strain. All these phenotypes are similar to ones caused by pms1, mlhl and msh2 mutations. In contrast to these mutations, hsm3-1 increases the frequency of ade mutations induced by 6-HAP and UV light. Epistasis analysis of double mutants shows that the PMS1 and HSM3 genes control different mismatch repair systems. The HSM3 gene maps to the right arm of chromosome II, 25 cM distal to the HIS7 gene. Strains that bear a deleted open reading frame YBR272c have the genetic properties of the hsm3 mutant. The HSM3 product shows weak similarity to predicted products of the yeast MSH genes (homologs of the Escherichia coli mutS gene). The HSM3 gene may be a member of the yeast MutS homolog family, but its function in DNA metabolism differs from the functions of other yeast MutS homologs.

Abstract
A subset of sporadic colorectal tumors and most tumors developing in hereditary nonpolyposis colorectal cancer patients display frequent alterations in microsatellite sequences. Such tumors have been thought to manifest replication errors (RER+), but the basis for the alterations has remained conjectural. We demonstrate that the mutation rate of (CA)n repeats in RER+ tumor cells is at least 100-fold that in RER- tumor cells and show by in vitro assay that increased mutability of RER+ cells is associated with a profound defect in strand-specific mismatch repair. This deficiency was observed with microsatellite heteroduplexes as well as with heteroduplexes containing single base-base mismatches and affected an early step in the repair pathway. Thus, a true mutator phenotype exists in a subset of tumor cells, the responsible defect is likely to cause transitions and transversions in addition to microsatellite alterations, and a biochemical basis for this phenotype has been identified.

Abstract
The genetic activity of 2-amino-N6-hydroxyadenine or 2-amino-N-hydroxylaminopurine (AHA) and N6-hydroxyadenine or 6-N-hydroxylaminopurine (HAP) was studied in S. typhimurium, E. coli and Saccharomyces cerevisiae strains. AHA was a more potent mutagen for bacteria and a less potent mutagen for yeast than HAP. The mutagenic activity of analogs was not influenced by excision, mutagenic or double-strand DNA repair mutations. On the other hand, the uvrBdel mutation has a drastic effect on the mutagenicity and toxicity of both analogs in the Salmonella strains studied. HAP was a very potent mutagen in yeast with a low capability of inducing mitotic recombination contrary to common mutagens, possessed unique intergenic specificity and was able to induce mutations in diploids at rather high frequency.
