SUMO1-Dha

SUMO1-Dha

details

SUMO1-Dha (UbiQ-116) (Dha= dehydroalanine) is a unique first of its kind activity based probe for the SUMO ligation pathway. It is based on the SUMO1 sequence in which the C-terminal Gly has been replaced by a dehydroalanine residue. The native Cys52 has been mutated to a Ser residue. UbiQ-116 is processed in a native manner by SUMO 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 enzymes, thereby creating a covalent bond (see figure).
