Catalysis of Transesterification Reactions by a Self-Assembled Nanosystem
Histidine-containing peptides self-assemble on the surface of monolayer protected gold nanoparticles to form a catalytic system for transesterification reactions. Self-assembly is a prerequisite for catalysis, since the isolated peptides do not display catalytic activity by themselves. A series of catalytic peptides and substrates are studied in order to understand the structural parameters tha...

متن کاملTransesterification reactions catalyzed by chymotrypsin.
As recently reported, the behavior of acetyl chymotrypsin with ethanol consists in a rapid transfer of the single acetyl group to that alcohol with the formation of ethyl acetate (1). Thus, the splitting of nitrophenyl acetates by chymotrypsin, faster in ethanolic than in aqueous solutions, may be explained by the formation of acetyl chymotrypsin as an intermediate and its subsequent preferenti...
متن کاملTransesterification reactions catalyzed by papain.
The hydrolysis of a series of esters of benzoyl-L-arginine and glycylglycine by papain has been examined in mixtures of water with various alcohols in the pH range of 5 to 6. The presence of straight chain alcohols resulted in an apparent inhibition of acid release. It was shown that this inhibition could, in part, be accounted for by papain-catalyzed transesterification reactions between the v...
متن کاملTransient signal generation in a self-assembled nanosystem fueled by ATP
A fundamental difference exists in the way signal generation is dealt with in natural and synthetic systems. While nature uses the transient activation of signalling pathways to regulate all cellular functions, chemists rely on sensory devices that convert the presence of an analyte into a steady output signal. The development of chemical systems that bear a closer analogy to living ones (that ...
