Cell rejuvenation and social behaviors promoted by LPS exchange in myxobacteria.
Bacterial cells in their native environments must cope with factors that compromise the integrity of the cell. The mechanisms of coping with damage in a social or multicellular context are poorly understood. Here we investigated how a model social bacterium, Myxococcus xanthus, approaches this problem. We focused on the social behavior of outer membrane exchange (OME), in which cells transientl...

نظر به اهمیت و تاثیر روزافزون عوامل روانی – اجتماعی در سلامت جسمی و تاثیر عوامل روان شناختی در بروز بیماریهای مختلف از جمله بیماریهای قلبی و عروقی این پژوهش با هدف کلی بررسی ارتباط تیپ شخصیتی d ، حمایت اجتماعی و خود دلسوزی در پیش بینی رفتارهای بهداشتی بیماران کرونر قلبی و تعیین تفاوت بین بیماران کرونر قلبی با و بدون جراحی و افراد سالم در این متغیرها و رفتارهای بهداشتی آنان، انجام گرفت. جامعه آ...
15 صفحه اولDNA Strand Exchange Promoted by RecA K72R
Replacement of lysine 72 in RecA protein with arginine produces a mutant protein that binds but does not hydrolyze ATP. The protein nevertheless promotes DNA strand exchange (Rehrauer, W. M., and Kowalczykowski, S. C. (1993) J. Biol. Chem. 268, 1292–1297). With RecA K72R protein, the formation of the hybrid DNA product of strand exchange is greatly affected by the concentration of Mg in ways th...
متن کاملCell Contact–Dependent Outer Membrane Exchange in Myxobacteria: Genetic Determinants and Mechanism
Biofilms are dense microbial communities. Although widely distributed and medically important, how biofilm cells interact with one another is poorly understood. Recently, we described a novel process whereby myxobacterial biofilm cells exchange their outer membrane (OM) lipoproteins. For the first time we report here the identification of two host proteins, TraAB, required for transfer. These p...
متن کاملBiomineralization induced by Myxobacteria
Myxococcus xanthus is a Gram negative, non-pathogenic, common soil bacterium that belongs to the δsubdivision of the Proteobacteria. According to the data, it is demonstrated that, depending on the chemistry of the culture media, M. xanthus is able to induce the formation of phosphates (struvite, schertelite, newberyite), carbonates (calcite, Mg-calcite, vaterite) and sulfates (barite, taylorit...
