Abstract:
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.
