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 seven rounds of directed evolution the enzymatic efficiency of the original 74 amino acid residue catalyst was improved more than 220-fold to achieve a kcat value higher than that of catalytic antibodies for the same reaction, still preserving allosteric regulation.
