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, (–)-pinoresinol reductase]. Isolated from the plants Thuja plicata (western red cedar) [1] and Linum corymbulosum [2].
