2132. In-situ XAS study of catalytic N[sub]2O decomposition over CuO/CeO[sub]2 catalystsMaxim Zabilsky, Iztok Arčon, Petar Djinović, Elena Tchernychova, Albin Pintar, 2021, izvirni znanstveni članek Opis: We performed in‐situ XAS study of N 2 O decomposition over CuO/CeO 2 catalysts. The Cu K‐edge and Ce L 3 ‐edge XANES and EXAFS analyses revealed the dynamic and crucial role of Cu 2+ /Cu + and Ce 4+ /Ce 3+ ionic pairs during the catalytic reaction. We observed the initial formation of reduced Cu + and Ce 3+ species during activation in helium atmosphere at 400 °C, while concentration of these species decreased significantly during steady‐state nitrous oxide degradation reaction (2500 ppm N 2 O in He at 400 °C). In‐situ EXAFS analysis further revealed a crucial role of copper‐ceria interface in this catalytic reaction. We observed dynamic changes in average number of Cu‐Ce scatters under reaction conditions, indicating an enlarging the interface between both copper and ceria phases, where electron and oxygen transfer occurs.

2140. Simultaneous ternary extension of DNA catalyzed by a trimeric replicase assembled in vivoAlejandro Montón Silva, Fabio Lapenta, Alessandra Stefan, Fabrizio Dal Piaz, Alessandro Ceccarelli, Alessandro Perrone, Alejandro Hochkoeppler, 2015, izvirni znanstveni članek Opis: According to current models, dimeric DNA Polymerases coordinate the replication of DNA leading and lagging strands. However, it was recently shown that trimeric DNA Polymerases, assembled in vitro, replicate the lagging strand more efficiently than dimeric replicases. Here we show that the τ, α, ε, and θ subunits of Escherichia coli DNA Polymerase III can be assembled in vivo, yielding the trimeric τ3α3ε3θ3 complex. Further, we propose a molecular model of this complex, whose catalytic action was investigated using model DNA substrates. Our observations indicate that trimeric DNA replicases reduce the gap between leading and lagging strand synthesis.
