Enzyme Information

1.23.1.3	(-)-pinoresinol reductase. based on mapping to UniProt Q9LD14 (-)-lariciresinol + NADP(+) = (-)-pinoresinol + NADPH. -!- The reaction is catalyzed 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). -!- Isolated from the plants Thuja plicata (western red cedar), Linum perenne (perennial flax) and Arabidopsis thaliana (thale cress).
1.23.1.4	(-)-lariciresinol reductase. based on mapping to UniProt Q9LD14 (+)-secoisolariciresinol + NADP(+) = (-)-lariciresinol + NADPH. -!- The reaction is catalyzed in vivo in the opposite direction to that shown. -!- A multifunctional enzyme that also reduces (-)-pinoresinol (EC 1.23.1.3). -!- Isolated from the plants Thuja plicata (western red cedar) and Linum corymbulosum.
1.23.1.1	(+)-pinoresinol reductase. based on mapping to UniProt Q9LD14 (+)-lariciresinol + NADP(+) = (+)-pinoresinol + NADPH. -!- The reaction is catalyzed in vivo in the opposite direction to that shown. -!- A multifunctional enzyme that further reduces the product to the lignan (-)-secoisolariciresinol (EC 1.23.1.2). -!- Isolated from the plants Forsythia intermedia, Thuja plicata (western red cedar), Linum perenne (perennial flax) and Linum corymbulosum. -!- The 4-pro-R hydrogen of NADH is transferred to the 7-pro-R position of lariciresinol.
