Webb11 rader · The Proteasome Activity Assay Kit is a relatively quick method for detection of intracellular proteasome activity. Testing of purified proteasome enzyme, in vitro … WebbIn eukaryotes, damaged or unneeded proteins are typically degraded by the ubiquitin-proteasome system. In this system, the protein substrate is often first covalently modified with a chain of ubiquitin polypeptides. This chain serves as a signal for delivery to the 26S proteasome, a 2.5-MDa, ATP-dependent multisubunit protease complex. original burkett pecan tree
