MetaCyc Reaction: 1.23.1.4

Superclasses: Reactions Classified By Conversion Type Simple Reactions Chemical Reactions
Reactions Classified By Substrate Small-Molecule Reactions

EC Number: 1.23.1.4

Enzymes and Genes:
(+)-pinoresinol/(-)-lariciresinol reductase Inferred from experiment : PLR ( Linum perenne )
(+)-pinoresinol/(+)-lariciresinol reductase Inferred from experiment : PLR_Tp1 ( Thuja plicata )

In Pathway: justicidin B biosynthesis , matairesinol biosynthesis

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.

Most BioCyc compounds have been protonated to a reference pH value of 7.3, and some reactions have been computationally balanced for hydrogen by adding free protons. Please see the PGDB Concepts Guide for more information.

Mass balance status: Balanced.

Enzyme Commission Primary Name: (–)-lariciresinol reductase

Enzyme Commission Synonyms: pinoresinol/lariciresinol reductase, pinoresinol-lariciresinol reductases, (-)-pinoresinol-(-)-lariciresinol reductase, PLR

Standard Gibbs Free Energy (ΔrG in kcal/mol): -1.0134888 Inferred by computational analysis [Latendresse13]
