2M3S - PubMed Abstract:
It only takes one mutation: a strategically placed single mutation in a non-enzymatic protein scaffold produced AlleyCat, a small, allosterically regulated catalyst of Kemp elimination. In only 7 rounds of directed evolution enzymatic efficiency of the original 74 amino acid residue catalyst was improved more than 220-fold to achieve k cat value higher than that of catalytic antibodies for the same reaction, still preserving allosteric regulation.
