Determinants of entry exclusion within Eex and TraG are cytoplasmic.
We report here functional and topological analyses of TraG and Eex, the donor and recipient cell inner membrane proteins that mediate entry exclusion in the SXT/R391 family of integrative conjugative elements. We found that the exclusion-determining regions of the Eex variants EexS (SXT) and EexR (R391) are located in distinct yet overlapping regions of the proteins. Unexpectedly, the carboxyl-...
متن کاملCompetitive Exclusion between Piroplasmosis and Anaplasmosis Agents within Cattle
There are about 869 species of ticks described so far [1], most of which are responsible for the transmission of a huge diversity of microorganisms belonging to almost all the trees of life (viruses, bacteria, protozoa, fungi, and nematodes) [2–4]. Despite the strong opportunity for interaction between these pathogenic species, little is known about the competitive interactions between tick-bor...
متن کاملSize exclusion and diffusion of fluoresceinated probes within collagen fibrils.
The diffusion of fluoresceinated probes inside single collagen fibrils was investigated by imaging the migration of fluorescence along the fibrils in oil and by monitoring fluorescence recovery after photobleaching (FRAP). Probes were excluded from the fibrils according to their size. Probes that were not excluded diffused in the fibrils, but FRAP occurred 6 x 10(-4) times more slowly than in w...
متن کاملInclusion-exclusion meets exclusion
When evaluating the inclusion-exclusion expansion N0 −N(1) −N(2) − · · ·+N(1, 2) +N(1, 3) + · · · many of the terms N(· · ·) may turn out to be zero, and hence should be discarded beforehand. Often this can be done.
متن کاملThe Radionuclides in Lake Ecosystems Within The Chernobyl Accident Exclusion Zone: Ten Years of Researches
During 1997-2007 we studied distribution and dynamics of main radionuclides and their biological significance in lake ecosystems within the 10-km inner exclusion zone around the destroyed unit of the Chernobyl nuclear power plant. The main objects of our studies were bottom sediments, water, seston, and different species of hydrobionts from Azbuchin Lake, Dalekoye-1 Lake and Glubokoye Lake. Sel...
