The functional diversity of protein lysine methylation
Large-scale characterization of post-translational modifications (PTMs), such as phosphorylation, acetylation and ubiquitination, has highlighted their importance in the regulation of a myriad of signaling events. While high-throughput technologies have tremendously helped cataloguing the proteins modified by these PTMs, the identification of lysine-methylated proteins, a PTM involving the tran...
متن کاملStructural basis for multiple ligand specificity of the periplasmic lysine-, arginine-, ornithine-binding protein.
The substrate-binding site of a protein with multiple specificity should satisfy geometric and energetic complementarity for several different substrates. The structural basis of the multiple ligand specificity of the periplasmic lysine-, arginine-, ornithine-binding protein (LAO) was investigated by determining and analyzing the structures of the protein unliganded and liganded with each of th...
متن کاملStructural basis for lower lysine methylation state-specific readout by MBT repeats of L3MBTL1 and an engineered PHD finger.
Human L3MBTL1, which contains three malignant brain tumor (MBT) repeats, binds monomethylated and dimethylated lysines, but not trimethylated lysines, in several histone sequence contexts. In crystal structures of L3MBTL1 complexes, the monomethyl- and dimethyllysines insert into a narrow and deep cavity of aromatic residue-lined pocket 2, while a proline ring inserts into shallower pocket 1. W...
متن کاملTranslational roles of elongation factor 2 protein lysine methylation.
Methylation of various components of the translational machinery has been shown to globally affect protein synthesis. Little is currently known about the role of lysine methylation on elongation factors. Here we show that in Saccharomyces cerevisiae, the product of the EFM3/YJR129C gene is responsible for the trimethylation of lysine 509 on elongation factor 2. Deletion of EFM3 or of the previo...
متن کاملStructural basis of the methylation specificity of R.DpnI
R.DpnI consists of N-terminal catalytic and C-terminal winged helix domains that are separately specific for the Gm6ATC sequences in Dam-methylated DNA. Here we present a crystal structure of R.DpnI with oligoduplexes bound to the catalytic and winged helix domains and identify the catalytic domain residues that are involved in interactions with the substrate methyl groups. We show that these m...
