BRITE hierarchy
Sysname
(+)-lariciresinol:NADP+ oxidoreductase
Reaction(IUBMB)
(+)-lariciresinol + NADP+ = (+)-pinoresinol + NADPH + H+ [RN:R10225]
Reaction(KEGG)
Substrate
(+)-lariciresinol [CPD:C10646];
NADP+ [CPD:C00006]
Product
(+)-pinoresinol [CPD:C05366];
NADPH [CPD:C00005];
H+ [CPD:C00080]
Comment
The reaction is catalysed 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, (+)-lariciresinol reductase]. Isolated from the plants Forsythia intermedia [1,2], Thuja plicata (western red cedar) [3], Linum perenne (perennial flax) [5] and Linum corymbulosum [6]. The 4-pro-R hydrogen of NADH is transferred to the 7-pro-R position of lariciresinol [1].
