    摘要: There is provided a method for producing free polyubiquitin chains linked through a single desired lysine residue, comprising the steps of: (a) selecting an E3 ubiquitin ligase enzyme which is homologous to mammalian HECT E3 ligases and possesses the desired lysine residue specificity; (b) incubating the E3 enzyme with an E1 ubiquitin activating enzyme, an E2 ubiquitin conjugating enzyme and monomeric ubiquitin; and (c) if undesired linkages are present, removing the undesired linkages by exposure to a DUB enzyme having the appropriate specificity.
