- Abstract:
-
NMR techniques and 8-anilino-1-napthalenesulphonate (ANS) binding studies have been used to characterize the apo state of a variant of cytochrome c(552) from Hydrogenobacter thermophilus. In this variant the two cysteines that form covalent thioether linkages to the heme group have been replaced by alanine residues (C11A/C14A). CD studies show that the apo state contains approximately 14% helical secondary structure, and measurements of hydrodynamic radii using pulse field gradient NMR method...
