Horseradish peroxidase biological function

Another reaction of heteroatom oxidation is that of S-oxidation, which leads to the synthesis of sulfoxides, a reaction not very common in the plant cell biochemical factory. Enantiomerically pure sulfoxides are important chiral synthons in asymmetric synthesis, in particular in enantio-selective carbon-carbon bond formation [77]. The sulfoxide functional group is involved in different biological activities, and optically pure sulfoxides are of great pharmaceutical interest [82]. However, plant peroxidases, such as horseradish peroxidase, catalyze the enantio-selective sulfoxidation of alkyl aryl sulfides ...
