Glossary:

(–)-lariciresinol = 4-[(2R,3S,4S)-4-[(4-hydroxy-3-methoxyphenyl)methyl]-3-(hydroxymethyl)oxolan-2-yl]-2-methoxyphenol
(–)-pinoresinol = (1R,3aS,4R,6aS)-4,4′-(tetrahydro-1H,3H-furo[3,4-c]furan-1,4-diyl)bis(2-methoxyphenol)

Other name(s):

pinoresinol/lariciresinol reductase; pinoresinol-lariciresinol reductases; (–)-pinoresinol-(–)-lariciresinol reductase; PLR

Systematic name:

(–)-lariciresinol:NADP⁺ oxidoreductase

Comments:

The reaction is catalysed in vivo in the opposite direction to that shown. A multifunctional enzyme that usually further reduces the product to (+)-secoisolariciresinol [EC 1.23.1.4, (–)-lariciresinol reductase]. Isolated from the plants Thuja plicata (western red cedar) [1], Linum perenne (perennial flax) [2] and Arabidopsis thaliana (thale cress) [3].
