A bacterial ATP-dependent, enhancer binding protein that activates the housekeeping RNA polymerase
Article Abstract:
Promoters in bacteria are usually thought to be transcriptionally activated by one of two general methods in gene regulation. A third mechanism has been identified in the photosynthetic bacterium Rhodobacter capsulatus, one that has properties of both of the known methods. An ATP-dependent, enhancer-binding protein activates the RNA polymerase responsible for housekeeping. There are some related mechanistic and evolutionary issues.

Regulation of homologous recombination: Chi inactivates RecBCD enzyme by disassembly of the three subunits
Article Abstract:
Research shows that Chi regulates individual RecBCD enzyme molecules to form single recombinational exchanges. All three subunits of RecBCD enzymes are disassembled after interacting with a Chi recombination hot spot, and migrate separately during glycerol gradient and native gel processes. This finding supports the one enzyme/one exchange theory of recombination.
