Au1−xPdx bimetallic catalysts with low Pd entities on CeO2 nanorods delivered high activity and chemoselectivity for hydrogenation of halogenated quinolines. Improved chemoselectivity could be attributed to the selective adsorption configurations of halogenated quinolines on Au via tilted orientation rather than on Pd via flat orientation.

SummaryAccumulating evidence indicates that there is a critical role of the ubiquitin/proteasome pathway in the regulation of apoptosis. Among the important molecules that couple these two fundamental cellular activities are members of the inhibitor of apoptosis (IAP) protein family. In addition to their well-studied ability to directly bind and inhibit caspases, many IAPs contain RING domains that are necessary and sufficient to cause ubiquitylation and subsequent proteasome-mediated proteolysis. This review summarizes recent findings about the ubiquitin protein ligase activity of IAPs, and considers possible mechanisms for substrate selectivity.IUBMB Life, 57: 779 -786, 2005
