Identification and differential production of ubiquinone-8 in the bacterial predator Bdellovibrio bacteriovorus.
Bdellovibrio bacteriovorus 109J, a predatory bacterium with potential as a bacterial control agent, can exist in several lifestyles that differ both in predatory capacity and color. We determined that levels of ubiquinone-8 contribute to the distinctive but variable yellow color of different types of Bdellovibrio cells. Steady-state ubiquinone-8 concentrations did not differ markedly between co...

متن کاملAnkyrin-mediated self-protection during cell invasion by the bacterial predator Bdellovibrio bacteriovorus
Predatory Bdellovibrio bacteriovorus are natural antimicrobial organisms, killing other bacteria by whole-cell invasion. Self-protection against prey-metabolizing enzymes is important for the evolution of predation. Initial prey entry involves the predator's peptidoglycan DD-endopeptidases, which decrosslink cell walls and prevent wasteful entry by a second predator. Here we identify and charac...
متن کاملIdentification of Bdellovibrio bacteriovorus HD100 Bd0714 as a Nudix dGTPase.
Bdellovibrio bacteriovorus bacteria are predatory organisms that attack other gram-negative bacteria. Here, we report that Bd0714 is a Nudix dGTPase from B. bacteriovorus HD100 with a substrate specificity similar to that of Escherichia coli MutT and complements an E. coli mutT-deficient strain. We observed different transcription levels of the gene throughout the predator life cycle.
متن کاملCharacterizing the flagellar filament and the role of motility in bacterial prey-penetration by Bdellovibrio bacteriovorus
The predatory bacterium Bdellovibrio bacteriovorus swims rapidly by rotation of a single, polar flagellum comprised of a helical filament of flagellin monomers, contained within a membrane sheath and powered by a basal motor complex. Bdellovibrio collides with, enters and replicates within bacterial prey, a process previously suggested to firstly require flagellar motility and then flagellar sh...
