Probing chromatin-modifying enzymes with chemical tools Wolfgang
... While most PKMTs were first characterized as histone methyl transferases, it is now clear that these enzymes have several if not many non-histone targets. Conversely, most of the PRMTs were initially defined outside the context of chromatin – especially in methylation of ribosomal proteins. However, ...
