Osmium tetroxide probing of local DNA structure in linear and supercoiled plasmids containing curvature-inducing sequences.
Recombinant plasmids pK1A108, pK3A108, pK4A108 and pK5/6T217 containing 80 +/- 1 base pair inserts with different curvature-inducing sequences were studied using the DNA structure probe osmium tetroxide in the presence of pyridine (Os, py). The insertion sequences of the plasmids pK1A108, pK3A108, and pK4A108 are strongly related while the degree of curvature increases from pK1A108 (no curvatur...
متن کاملDNA Intercalators: Cutting plasmids in half
We have designed and synthesized novel intercalating compounds that efficiently hydrolyze supercoiled plasmid DNA lacking depurine/depyrimidine sites. These intercalators consist of conjugates of diamine and thia-heterocyclic naphthalimide. Surprisingly, the initial hydrolyzed products comprised fragments with half the length of the original plasmid. We suggest a mechanochemical mechanism that ...
متن کاملLinear DNA plasmids from Pichia etchellsii, Debaryomyces hansenii and Wingea robertsiae.
Linear DNA plasmids were found in the following yeasts: four strains of Kluyveromyces lactis, one of Debaryomyces hansenii, one of Wingea robertsiae and four of Pichia etchellsii. In each case, the plasmids were present as a pair of DNA molecules of different sizes. The plasmids of K. lactis strains were associated with a killer activity and their structure was similar to the known killer plasm...
متن کاملThe yeast linear DNA killer plasmids, pGKL1 and pGKL2, possess terminally attached proteins.
The terminal structures of linear DNA killer plasmids from yeast, pGKL1 and pGKL2, were analyzed. Results obtained by exonuclease treatments of these plasmids show that both pGKL plasmids have free hydroxyl 3'-ends and blocked 5'-ends. Electrophoretic analysis of the terminal restriction fragments treated with proteases revealed that pGKL1 and pGKL2 have proteins bound at 5'termini and that the...
متن کاملImmunomodulating compounds in Basidiomycetes
Mushrooms are distinguished as important food containing immunomodulating and anticancer agents. These compounds belong mostly to polysaccharides especially β-d-glucans. Among them, β-1,3-glucan with side chain β-1,6-glucose residues have more important roles in immunomodulating and antitumor activities. In this review, we have introduced polysaccharide mainly from Lentinula edodes and Agaricus...
