Histone arginine N methyltransferase

Histone-arginine N-methyltransferase (EC 2.1.1.125, histone protein methylase I, nuclear protein (histone) N-methyltransferase, protein methylase I, S-adenosyl-L-methionine:histone-arginine omega-N-methyltransferase) is an enzyme with systematic name S-adenosyl-L-methionine:histone-arginine Nomega-methyltransferase. This enzyme catalyses the following chemical reaction

S-adenosyl-L-methionine + histone-arginine ⇌ S-adenosyl-L-homocysteine + histone-Nomega-methyl-arginine

The enzyme forms the Nomega-monomethyl- and Nomega,Nomega'-dimethyl.
