In Vivo Bipartite Interaction Between the Hsp40 Sis1 and Hsp70 in Saccharomyces cerevisiae

In vivo bipartite interaction between the Hsp40 Sis1 and Hsp70 in Saccharomyces cerevisiae.

The essential Hsp40, Sis1, is a J-protein cochaperone for the Ssa class of Hsp70's of Saccharomyces cerevisiae. Sis1 is required for the maintenance of the prion [RNQ(+)], as Sis1 lacking its 55-amino-acid glycine-rich region (G/F) does not maintain [RNQ(+)]. We report that overexpression of Sis1DeltaG/F in an otherwise wild-type strain had a negative effect on both cell growth and [RNQ(+)] mai...

the relationship between learners critical thinking ability and their performance in the reading sections of the tofel and ielts test

the study reflected in this thesis aims at finding out relationships between critical thinking (ct), and the reading sections of tofel and ielts tests. the study tries to find any relationships between the ct ability of students and their performance on reading tests of tofel and academic ielts. however, no research has ever been conducted to investigate the relationship between ct and the read...

Direct interactions between molecular chaperones heat-shock protein (Hsp) 70 and Hsp40: yeast Hsp70 Ssa1 binds the extreme C-terminal region of yeast Hsp40 Sis1.

Heat-shock protein 40 (Hsp40) enables Hsp70 to play critical roles in a number of cellular processes, such as protein folding, assembly, degradation and translocation in vivo. Hsp40 recognizes and binds non-native polypeptides and delivers them to Hsp70. Then Hsp40 stimulates the ATPase activity of Hsp70 to fold the polypeptides. By using yeast Hsp40 Sis1 and yeast Hsp70 Ssa1 as our model prote...

Interaction between Saccharomyces cerevisiae and chrysotile.

The interaction between Saccharomyces cerevisiae and chrysotile fibers was studied by scanning electron microscopy. The yeast cells adhere preferentially to the fibrils. In the extreme case, all the adhered fibrils were broken, resulting in a complete coverage of the surface. The chrysotile covered cells showed less buds, but retained metabolic capacities, and were fully active in fermentation ...
