"Additionally , they are more potent than the abovementioned Leucettamol A ( Fig. 5 ) .424 CC0651 , a small-molecule selective allosteric site inhibitor of the E2 enzyme hCdc34 , can block the ubiquitination and degradation of p27 and then inhibit tumor cell proliferation ( Fig. 5 ) .425 In addition , small-molecule microarray-based screening has also been successfully used to identify the inhibitor of the SUMO E2 enzyme Ubc9 , and a few small-molecule inhibitors have been found.426 Targeting DUB activity As mentioned , ubiquitination is a dynamic and reversible process , and DUBs mediate the removal and processing of Ub or polyubiquitin chains from ubiquitinated proteins ."
