Dynamics on individual reaction sites in steady-state carbon monoxide oxidation on stepped platinum(113)
Article Abstract:
Angle-resolved kinetic and velocity measurements were used in studying the reaction kinetics and dynamics of carbon monoxide oxidation on a stepped Pt(113) = (s)2(111) x (001) surface. Results indicated that carbon dioxide desorption was sharply collimated along the (111) and (OO1) sites. The preference of the (111) site was suppressed with increasing CO pressure above 520 K in the active region. Site switching occurred under restricted conditions when the temperature was below 520 K.

Application to Ru-modified cytochrome c
Article Abstract:
A study was conducted to analyze the use of a model that characterizes the coupling of protein fluctuations to electron transfer in Ru-modified cytochrome c. Two sets of energy minimizations were carried out. the protein fluctuations were modeled by collective normal modes supporting reaction field energies. Experimental results indicated the applicability of the model to an electron transfer protein.

Methionine redox controlled crystallization of biosynthetic silk spidroin
Article Abstract:
The oxidation state of methionine triggers affects the tendency of the recombinant spider dragline silk model protein to adopt a beta-sheet conformation. The ability of the oxidized methionine triggers to inhibit formation of the beta-sheet conformation is even greater when beta-sheet crystallinity is considered.
