Effects of cysteine introduction into three homologous cytochromes C.
A cysteine residue was systematically introduced into three homologous cytochromes c from Hydrogenobacter thermophilus, Hydrogenophilus thermoluteolus, and Pseudomonas aeruginosa at a conserved position. The H. thermoluteolus variant showed the most decreased thermal stability as compared with the wild type, which might have been due in part to crosslinked polymer formation. The effects of cysteine introduction differed even at the conserved position in these homologous proteins.
