His6-Ubiquitin Mutant K11R

Price: 
$85
Quantity: 
1 mg
Mutation of lysine 11 to arginine renders ubiquitin (Ub) unable to form poly-Ub chains via lysine 11 linkages with other Ub molecules. Ub K11R can form an E1-catalyzed active thioester at the C-terminus allowing the molecule to be transferred to the lysines of substrate proteins. Ideal for the reduction in poly-Ub chain length/conjugation rates and determining if poly-Ub chains are K11 linked.
