EC Number:

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the direction in which it was curated.

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.

a [protein] N6,N6-dimethyl-L-lysine + 2-oxoglutarate + oxygen → a [protein] N6-methyl-L-lysine + succinate + formaldehyde + CO2 ,
a [protein] N6-methyl-L-lysine + 2-oxoglutarate + oxygen + H+ → a [protein]-L-lysine + succinate + formaldehyde + CO2

Standard Gibbs Free Energy (ΔrG in kcal/mol): -164.16656 Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
Requires iron(II). Of the seven potential methylation sites in histones H3 (K4, K9, K27, K36, K79) and H4 (K20, R3) from HeLa cells, the enzyme is specific for Lys-36. Lysine residues exist in three methylation states (mono-, di- and trimethylated). The enzyme preferentially demethylates the dimethyl form of Lys-36 (K36me2), which is its natural substrate, to form the monomethyl and unmethylated forms of Lys-36. It can also demethylate the monomethyl- but not the trimethyl form of Lys-36.
