Abstrakt | Competence for genetic transformation is a physiological state that enables cells to bind and internalize exogenous DNA. In Bacillus subtilis the transcription factor ComK is a key regulator of competence. Using B. subtilis DNA microarrays, we have defined the ComK regulon. Many genes are up-regulated and a few a repressed by ComK. Many of the ComK-induced genes are organized in operons and several are preceded by apparent ComK-box promoter motifs. In addition to previously known genes required for DNA uptake and recombination, other ComK-induced genes that are probably involved in DNA repair and in the uptake and utilization of nutritional sources have been identified. We conclude that the ComK regulon defines a transiently dormant state, of which competence for genetic transformation is only one feature. We suggest the term "K-state" as a broader definition of this stress response. (Abstract truncated at 2000 characters) | |
