Description
5-carboxyRh110-Nedd8-Dha (UbiQ-122) is an activity-based probe for Nedd8 E1, E2 and E3 ligases. It is based on the Nedd8 sequence in which the C-terminal Gly76 has been replaced by a dehydroalanine (Dha) residue. The N-terminus is labeled with the green fluorescent 5-carboxyrhodamine110 dye (cRh110). It has been prepared by total chemical synthesis and is therefore well-defined in terms of dye site. UbiQ-122 is processed in a native manner by E1, E2 and E3 ligases and during this process, it forms an electrophilic intermediate that can react with the active site Cys residue of the E1, E2 and E3 enzyme, thereby creating a covalent bond.
