His6-Ahx-Ahx-SUMO2-VPS (UbiQ-237) is an activity-based probe for SUMO proteases that is prepared by total chemical synthesis. It contains a C-terminal vinyl pentynyl sulfone (VPS) electrophile (Figure 1) and an N-terminal His6 sequence which allows for sensitive identification or purification by anti-His6 antibodies and/or anti-His6-agarose. The VPS electrophile allows for post-labeling modification of cross-linked UbiQ-237::SENP complexes by using click chemistry with for example biotin-azide.
