Current study results from the report, 'Mechanism of the CO-sensing heme protein CooA: new insights from the truncated heme domain and UVRR spectroscopy,' have been published. "The bacterial CO-sensing heme protein CooA activates expression of genes whose products perform CO-metabolism by binding its target DNA in response to CO binding. The required conformational change has been proposed to result from CO-induced displacement of the heme and of the adjacent C-helix, which connects the sensory and DNA-binding domains," investigators in the United States report.

"Support for this proposal comes from UV Resonance Raman (UVRR) spectroscopy, which reveals a more...
