Abstract
There is great interest in increasing proteins' stability to enhance their utility as biocatalysts, therapeutics, diagnostics and nano-materials. Directed evolution is a powerful, but experimentally strenuous approach. Computational methods offer attractive alternatives. However, due to the limited reliability of predictions and potentially antagonistic effects of substitutions, only single-point mutations are usually predicted in silico, experimentally verified, then recombined in multiple-point mutants. Thus, substantial screening is still required. Here we present a robust computational strategy for predicting highly stable multiple-point mutants, called FireProt, combining energy- and evolution-based approaches with smart filtering to identify additive stabilizing mutations. We show that thermostability of the model enzyme haloalkane dehalogenase DhaA can be substantially increased (dTm , 24 o C) by constructing and characterizing as few as six multiple-point mutants. The method is generally applicable to all proteins with known tertiary structure and homologous sequences, and should facilitate rapid development of robust proteins for biomedical and biotechnological applications.
