(R)-selective hydroxynitrile lyase variants with a cupin fold having improved substrate scope and the use thereof

摘要

The present invention relates to an improved recombinant cupin-hydroxynitrile lyase (HNL), which is capable to catalyze the asymmetric cyanohydrin reaction, wherein the recombinant cupin-HNL comprises at least one amino acid substitution, preferably at least three substitutions.
