Biochemical basis for dominant mutations in the Saccharomyces cerevisiae MSH6 gene.
Here, the ATP-binding, ATP hydrolysis, mispair-binding, sliding clamp formation, and Mlh1-Pms1 complex interaction properties of dominant mutant Msh2-Msh6 complexes have been characterized. The results demonstrate two mechanisms for dominance. In one, seen with the Msh6-S1036P and Msh6-G1067D mutant complexes, the mutant complex binds mispaired bases, is defective for ATP-induced sliding clamp ...
متن کاملinvestigating the integration of translation technologies into translation programs in iranian universities: basis for a syllabus design in translation technology
today, information technology and computers are indispensable tools of any profession and translation technologies have become an indispensable part of translator’s workstation. with the increasing demands for high productivity and speed as well as consistency and with the rise of new demands for translation and localization, it is necessary for translators to be familiar with market demands an...
EXO1 and MSH6 are high-copy suppressors of conditional mutations in the MSH2 mismatch repair gene of Saccharomyces cerevisiae.
In Saccharomyces cerevisiae, Msh2p, a central component in mismatch repair, forms a heterodimer with Msh3p to repair small insertion/deletion mismatches and with Msh6p to repair base pair mismatches and single-nucleotide insertion/deletion mismatches. In haploids, a msh2Delta mutation is synthetically lethal with pol3-01, a mutation in the Poldelta proofreading exonuclease. Six conditional alle...
متن کاملAnalysis of Tetrads from the yeast Saccaromyces cerevisiae
When normally haploid yeast cells of two different mating types encounter each other, they fuse to form a diploid zygote (this constitutes a cross), which immediately undergoes meiosis to regenerate four individual haploid spores – a tetrad (the equivalent of an F1 generation). Since each meiotic tetrad is contained in a sac-like structure called an ascus, it can be recovered as an intact group...
متن کاملthe search for the self in becketts theatre: waiting for godot and endgame
this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
