An efficient total chemical synthesis of site-specifically sumoylated histone H4 was undertaken to generate homogenously modified mononucleosomes. These were tested as substrates in biochemical assays with the histone H2B-specific ubiquitin ligases Rad6 and Bre1, which revealed the strong inhibition of H2B ubiquitylation by SUMO. This novel negative biochemical crosstalk between SUMO and ubiquitin was also confirmed to exist in human cells. [ABSTRACT FROM AUTHOR] |
