Effects of biomineralization peptide topology on the structure and catalytic activity of Pd nanomaterials.

چکیده
Highly branched, coral-like Pd nanostructures were formed using a biomineralization peptide conjugated to an oligomeric peptide that simultaneously controls the spatial orientation, arrangement and valency. The Pd nanocoral showed very high catalytic activity in the reduction of nitrophenol. The results highlight the importance of topological arrangement in nanostructure formation and catalytic activity.

In the present study we attempted to correlate the structure and function of the cry11a (72 kDa) and cry4a (135 kDa) proteins of Bacillus thuringiensis var israelensis. Homology modeling and secondary structure predictions were done to locate most probable regions for finding helices or strands in these proteins. The JPRED (JPRED consensus secondary structure prediction server) secondary struct...
