Circular permutation in the Ω-loop of TEM-1 β-lactamase results in improved activity and altered substrate specificity.
Generating diverse protein libraries that contain improved variants at a sufficiently high frequency is critical for improving the properties of proteins using directed evolution. Many studies have illustrated how random mutagenesis, cassette mutagenesis, DNA shuffling and similar approaches are eff...
