Involved in linalool degradation. Catalyzes the reversible isomerization of linalool to geraniol. Does not show stereospecificity towards linalool isomers and acts equally well on both (R) and (S)-linalool. Cannot use the monoterpenoids citronellol and nerol as substrates. linalool = (2E)-geraniol Optimum pH is around 8.0. Optimum temperature is 35 degrees Celsius. Terpene metabolism; monoterpene degradation.
