Glossary:

(–)-lariciresinol = 4-[(2R,3S,4S)-4-[(4-hydroxy-3-methoxyphenyl)methyl]-3-(hydroxymethyl)oxolan-2-yl]-2-methoxyphenol
(+)-secoisolariciresinol = (2S,3S)-2,3-bis[(4-hydroxy-3-methoxyphenyl)methyl]butane-1,4-diol

Other name(s):

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

Systematic name:

(+)-secoisolariciresinol:NADP⁺ oxidoreductase

Comments:

The reaction is catalysed in vivo in the opposite direction to that shown. A multifunctional enzyme that also reduces (–)-pinoresinol [EC 1.23.1.3, (–)-pinoresinol reductase]. Isolated from the plants Thuja plicata (western red cedar) [1] and Linum corymbulosum [2].
