The present invention relates to novel mutants with cyclase activity and use thereof in a method for biocatalytic cyclization of terpenes, such as in particular for the production of isopulegol by cyclization of citronellal; a method for the preparation of menthol and methods for the biocatalytic conversion of further compounds with structural motifs similar to terpene.
