Structure and dynamics of substrate binding (cefotaxime) to the catalytic pocket of the mononuclear zinc-beta-lactamase from Bacillus cereus are investigated by molecular dynamics simulations. The calculations, which are based on the hydrogen-bond pattern ...
This paper describes the supramolecular organization of a novel de novo designed metalloprotein, which consists of two N-terminal terpyridine modified coiled-coil protein folding motif sequences held together by an iron(II) ion. The self-assembly of the me ...
Enzymes possessing the capacity to oxidize molecular hydrogen have developed convergently three class of enzymes leading to: [FeFe]-, [NiFe]-, and [FeS]-cluster-free hydrogenases. They differ in the composition and the structure of the active site metal ce ...
Femtosecond fluorescence-upconversion studies of aq. [Ru(bpy)3]2+ show a short-lived vibrationally hot emission of the singlet metal-to-ligand charge-transfer state, with an ultrafast intersystem crossing (~ 10 fs) to the triplet state at const. energy (th ...
The heterogeneous photoinduced electron transfer involving dyes adsorbed at the interface between two immiscible electrolyte solutions and redox molecules located in the adjacent phase manifests itself as photocurrent responses under potentiostatic conditi ...
Clusters and islands of Fe atoms have been prepared by noble gas buffer layer assisted growth as well as by standard molecular beam epitaxy on Pt substrates. Xe buffer layers have been utilized to promote the formation of compact, relaxed Fe clusters with ...
Two unsymmetrical ditopic hexadentate ligands designed for the simultaneous recognition of two different trivalent lanthanide ions have been synthesized, LAB2 and LAB3, where A represents a tridentate benzimidazole-pyridinebenzimidazole coordination unit, ...
We have determined the crystal structure of YodA, an Escherichia coli protein of unknown function. YodA had been identified under conditions of cadmium stress, and we confirm that it binds metals such as cadmium and zinc. We have also found nickel bound in ...
