label: protein-arginine omega-N asymmetric methyltransferase activity
label_lc: protein-arginine omega-n asymmetric methyltransferase activity
description: "Catalysis of the addition of a second methyl group to methylated peptidyl-arginine. Methylation is on the same terminal nitrogen (omega nitrogen) residue that was previously methylated, resulting in asymmetrical peptidyl-N(omega),N(omega)-dimethylated arginine residues."
