Protein Variants Comment Organism
A314V mutation does not change the product outcome Salvia divinorum
A314V/F255H mutation leads to the recovery of the ability to produce (-)-kolavenyl diphosphate of wild-type while retaining the acquired function of forming ent-copalyl diphosphate of mutant F255H Salvia divinorum
F255H mutation in direction to copalyl diphosphate synthase, mutant shows a complete switch of product specificity from (-)-kolavenyl diphosphate to ent-copalyl diphosphate Salvia divinorum
V200I mutation does not change the product outcome Salvia divinorum
