Stimulation of GLP activity by nucleosomes that are premethylated at H3K9. (A) Substrate description. (B,C) Histone methyltransferase activity assay at nucleosomes flanked by premodified nucleosomes with the wild-type GLP (B) or GLP catalytic mutant (C). (D) Histone methyltransferase activity assay at nucleosomes flanked by nucleosomes premodified at H3K27 with GLP. (E) Histone methyltransferase activity assay at nucleosomes flanked by H3K9 premodified nucleosomes with GLP 3A. (One microgram of recombinant enzymes and 1 μg of recombinant oligonucleosomes were used in the assay.)
