Protein
Bifunctional pinoresinol-lariciresinol reductase
Function
Reductase involved in the lignan justicidin B biosynthesis. Catalyzes the enantioselective conversion of (+)-pinoresinol into (+)-lariciresinol and of (-)-lariciresinol into (+)-secoisolariciresinol. Low activity with the other enantiomers. Abstracts the 4R-hydride from the NADPH cofactor during catalysis.
Similarity
Belongs to the NmrA-type oxidoreductase family. Isoflavone reductase subfamily.
