HA-Ahx-Ahx-Ub-VPS

details

HA-Ahx-Ahx-Ub-VPS (UbiQ-193) is an irreversible inhibitor of deubiquitinating enzymes (DUBs) that is prepared by chemical synthesis. It contains a vinyl pentynyl sulfone (VPS) warhead and N-terminal HA-tag (YPYDVPDYA). The HA tag is separated from the Ub N-terminus by two aminohexanoic acid (Ahx) linkers for efficient recognition of the tag. The VPS electrophile allows for post-labeling modification of covalent DUB::UbiQ-193 complexes by using click chemistry with for example biotin-azide.
