Abstract excerpt

The stability of the oxidized and reduced forms of three homologous cytochromes c from two thermophiles and one mesophile was systematically monitored by means of Soret absorption measurements in the presence of various concentrations of a denaturant, guanidine thiocyanate, at pH 7.0 at 25 degrees C. Thermophilic Hydrogenobacter thermophilus cytochrome c(552) was the most stable in both redox states, followed by...
