2XK5 - PubMed Abstract: 
Ubiquitination is a reversible post-translational modification that regulates a myriad of eukaryotic functions. Our ability to study the effects of ubiquitination is often limited by the inaccessibility of homogeneously ubiquitinated proteins. In particular, elucidating the roles of the so-called 'atypical' ubiquitin chains (chains other than Lys48- or Lys63-linked ubiquitin), which account for a large fraction of ubiquitin polymers, is challenging because the enzymes for their biosynthesis are unknown ...
