S-adenosyl-L-methionine + monomethylated histone H3(K9) | Arabidopsis thaliana | the SUVR4 product specificity shifts from di- to trimethylation in the presence of free ubiquitin. SUVR4 in vivo specifically converts monomethylated histone H3(K9) to trimethylated histone H3(K9) at transposons and pseudogenes | S-adenosyl-L-homocysteine + trimethylated histone H3(K9) | - |
