Also known as: IsoT

Isopeptidase T is a member of the high molecular weight ubiquitin C-terminal hydrolases (UCHs) that are a family of cysteine hydrolases that catalyze the hydrolysis of amides, esters and thioesters from the C-terminus of ubiquitin. This enzyme primarily disassembles free polyubiquitin chains linked through isopeptide bonds. This activity has a critical role in the recycling of Ub and in the regulation of the activity of the 26S proteasome.

Product Information
