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 [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.
