General description
Manufactured for Sigma by Boston Biochem., Inc.
Application
Proteasome Fraction II is ideal for demonstrating ubiquitin- and ATP-dependent degradation/conjugation of radiolabeled or immunodetectable substrates. Isopeptidase inhibitor and a proteasome inhibitor are highly recommended for the accumulation of ubiquitin protein conjugates. Typical assay concentration for FII is 0.5 - 4 mg/ml.
Biochem/physiol Actions
Essentially ubiquitin and ATP free. Contains E1, most E2s, UCHs, and the proteasome 20S and 26S isoforms.
Protein fraction of a cell extract that binds to anion-exchange resin.
Physical form
Solution in 25 mM HEPES, pH 7.6.
Storage Class
10 - Combustible liquids

In order to gain insight into the mechanisms that determine the selectivity of the ubiquitin proteolytic pathway, the protein substrate binding site of the ubiquitin-protein ligase system was identified and examined. Previous studies had shown that the ligase system consists

By affinity chromatography of a crude reticulocyte extract on ubiquitin-Sepharose, three enzymes required for the conjugation of ubiquitin with proteins have been isolated. One is the ubiquitin-activating enzyme (E1), which is covalently linked to the affinity column in the presence
