A Structure-Controlled Investigation of Lipase Enantioselectivity by a Path-Planning Approach

Abstract : A novel approach based on efficient path‐planning algorithms was applied to investigate the influence of substrate access on Burkholderia cepacia lipase enantioselectivity. The system studied was the transesterification of 2‐substituted racemic acid derivatives catalysed by B. cepacia lipase. In silico data provided by this approach showed a fair qualitative agreement with experimental results, and hence the potential of this computational method for fast screening of racemates. In addition, a collision detector algorithm used during the pathway searches enabled the rapid identification of amino acid residues hindering the displacement of substrates along the deep, narrow active‐site pocket of B. cepacia lipase and thus provided valuable information to guide the molecular engineering of lipase enantioselectivity.
