... sizes, shapes and stereochemis- tries of residues are critical and restrictive [13]. Systematic studies offer support for both views. For example, a mutant of T4 lysozyme with 10 mutations of core ... 57% of clones were active upon randomization of the six helix residues, and 23% were active upon additional randomization of six sheet-side residues. The frequency of act...
