PubMed Abstract:
SUV420H1 and SUV420H2 are two highly homologous enzymes that methylate lysine 20 of histone H4 (H4K20), a mark that has been implicated in transcriptional regulation. In this study, we present the high-resolution crystal structures of human SUV420H1 and SUV420H2 in complex with SAM, and report their substrate specificity. Both methyltransferases have a unique N-terminal domain and Zn-binding post-SET domain, and prefer the monomethylated histone H4K20 as a substrate in vitro. No histone H4K20 trimethylation activity was detected by our radioactivity-based assay for either enzyme, consistent with the presence of a conserved serine residue that forms a hydrogen bond with the target lysine side-chain and limits the methylation level.
