Sequence

Human ubiquitin (Accession Nr. P0CG47) conjugated to AMC.



Crossreactivity

Human



Label/Conjugates

AMC



Formulation

Liquid. In DMSO.



Other Product Data


Use:
Fluorogenic substrate for some ubiquitin-specific isopeptidases, based on the C-terminus derivatization of ubiquitin with 7-amino-4-methylcoumarin (AMC). Sensitive deubiquitinating enzyme substrate, useful for studying ubiquitin C-terminal hydrolytic activity when detection sensitivity or continuous monitoring is essential. Release of AMC fluorescence can be monitored with an excitation wavelength of 345nM and an emission wavelength of 445nM. Reaction conditions will need to be optimized for each specific application. We recommend an initial protein concentration of 0.1-1?M.

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
