Effect of carbon monoxide (CO) on the UV-vis spectrum of RoxA and Strep-LcpK30. The UV-vis difference spectra of RoxA and Lcp, as isolated, in the absence and presence of CO-saturated buffer were recorded. A strong reaction is detectable for RoxA compared to no change of the spectrum in the case of Strep-LcpK30.
