The overexpression and gene knockdown of StTRII alters tropinone reduction in vivo, and has great influence on calystegine accumulation, in contrast to genetic manipulation of isozyme St-TRI, EC 1.1.1.206, phenotypes, calystegine analysis, overview. A strong reduction of calystegines appears in the StTRII RNAi lines 741221

The mutant enzymes also remain to have the ability to reduce the 3-quinuclidinone and 4-methylcyclohexanone, although the Vmax of DnTR2-Y201V toward 4-methylcyclohexanone and 3-quinuclidinone are significantly lower (23 and 3fold decrease, respectively) than that of wild-type DnTR2 protein 740901
