This M1 linked di-ubiquitin was recombinantly expressed in E. coli, enzymatically conjugated, and purified via liquid chromatography.
The array of cellular processes initiated and regulated by ubiquitin has been partially explained by the structural diversity of differently linked ubiquitin chains. In a ubiquitin chain, ubiquitin moieties can be conjugated through one of their lysine residues (K6, K11, K27, K29, K33, K48 and K63) or the N-terminal methionine residue (M1), offering countless possibilities to assemble a specific polymer. Ubiquitin molecules can also be modified by other post-translational modifications, including acetylation and phosphorylation, adding another layer of ubiquitin signal regulation and diversification. This M1 linked linear di-ubiquitin was recombinantly expressed in E. coli, enzymatically conjugated, and purified via liquid chromatography.
