Abstract excerpt
Site-directed mutations have been introduced singly and in combination at residues lysine/arginine45 (CD3), histidine64 (E7), threonine67 (E10), and valine68 (E11) in pig and sperm whale myoglobins. The mutations probe the roles of these key distal pocket residues and represent attempts to mimic...
