Abstract

The O2 reactivity of an artificial biomolecular hydrogenase, the class="Gene">nickel binding protein (<class="Chemical">span class="Gene">NBP) is investigated. Kinetic analyses revealed a complete 4e- reduction of O2 to H2O under catalytic conditions with associated k0 for ET in the order of 10-6 cm s-1. Protein destabilization and S oxygenation are contributing factors to the deactivation of NBP under oxic conditions. Computational studies provided insight into the S oxygenation and the reaction intermediates of a proposed mechanistic pathway for O2 activation by NBP.
