2.1.1.355	3 S-adenosyl-L-methionine + a [histone H3]-L-lysine9	activity toward histones in chromatin. SUV39H1 trimethylates H3K9, thereby creating a binding site for HP1, which recruits SUV4-20H. This enzyme generates H4K20me3 using as a substrate the H4K20me1 generated by SET8. Consequently, SUV39H1 indirectly affects the methylation of H4K20 via two pathways: it modifies SET8, thereby enhancing its activity, and creates a site for the binding of SUV4-20H	3 S-adenosyl-L-homocysteine + a [histone H3]-N6,N6,N6-trimethyl-L-lysine9	-	?	448387
