Cytochrome c stability
WebAug 26, 2002 · Abstract. Native-state hydrogen exchange experiments under EX1 conditions can distinguish partially unfolded intermediates by their formation rates and identify the amide hydrogens exposed and protected in each. Results obtained define a cytochrome c intermediate seen only poorly before and place it early on the major unfolding pathway. WebNov 13, 2001 · The role of two tryptophans (Trp51 and Trp191) and six tyrosines (Tyr36, Tyr39, Tyr42, Tyr187, Tyr229, and Tyr236) in yeast cytochrome c peroxidase (CcP) has been probed by site-directed mutagenesis. A series of sequential mutations of these redox-active amino acid residues to the corresponding, less oxidizable residues in lignin …
