E. coli



Sequence

Human ubiquitin L73P mutant (Accession Nr. P0CG47).



Crossreactivity

Human



Formulation

Lyophilized from a solution in deionized water.



Other Product Data


Use:
Contains a mutation of leucine 73 to proline. Can form an E1-catalyzed active thioester at the C-terminus allowing the molecule to be transferred to E2 carrier proteins, and poss

y to E3 ligases and their substrates. Polyubiquitin chains generated using L73P are highly resistant to disassembly by deubiquitinases. Potential uses of this protein include generating ubiquitin conjugates that are more stable than their native counterparts in the presence of deubiquitinase enzymes. Able to form chains that are highly resistant to deubiquitinating enzyme activity. Reaction conditions will need to be optimized for each specific application. We recommend an initial protein concentration of 0.5-1mM.

Ubiquitin is a 76 amino acid (aa) protein that is ubiquitously expressed in all eukaryotic organisms. ubiquitin is highly conserved with 96% aa sequence identity shared between human and yeast ubiquitin, and 100% aa sequence identity shared between human and mouse ubiquitin. In mammals, four ubiquitin genes encode for two ubiquitin-ribosomal fusion proteins and two poly-ubiquitin proteins. Cleavage of the ubiquitin precursors by deubiquitinating enzymes gives rise to identical ubiquitin monomers each with a predicted molecular weight of 8.6 kDa. Conjugation of ubiquitin to target proteins involves the formation of an isopeptide bond between the C-terminal glycine residue of ubiquitin and a lysine residue in the target protein. This process of conjugation, referred to as ubiquitination or ubiquitylation, is a multi-step process that requires three enzymes: a ubiquitin-activating (E1) enzyme, a ubiquitin-conjugating (E2) enzyme, and a ubiquitin ligase (E3). ubiquitination is classically recognized as a mechanism to target proteins for degradation and as a result, ubiquitin was originally named ATP-dependent Proteolysis Factor 1 (APF-1). In addition to protein degradation, ubiquitination has been shown to mediate a variety of
