MetaCyc Reaction: 2.1.1.129

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

EC Number: 2.1.1.129

Enzymes and Genes:
myo-inositol 4-O-methyltransferase Inferred from experiment : imt1 ( Mesembryanthemum crystallinum )

In Pathway: pinitol biosynthesis I

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: inositol 4-methyltransferase

Enzyme Commission Synonyms: myo-inositol 4-O-methyltransferase, S-adenosyl-L-methionine:myo-inositol 4-O-methyltransferase, myo-inositol 6-O-methyltransferase

Standard Gibbs Free Energy (ΔrG in kcal/mol): -4.3599854 Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
The enzyme from the rice bean Vigna umbellata (Fabaceae) is highly specific for S-adenosyl-L-methionine. The enzyme also methylates 1L-1,2,4/3,5-cyclohexanepentol, 2,4,6/3,5-pentahydroxycyclohexanone, D,L-2,3,4,6/5-pentacyclohexanone and 2,2′-anhydro-2-C-hydroxymethyl-myo-inositol, but at lower rates than that of myo-inositol.
