H.</dc:contributor> <dcterms:abstract xml:lang="eng">The tungsten-iron-sulfur enzyme acetylene hydratase is a rather unique enzyme within the class of tungsten/molybdenum enzymes in the sense that it catalyzes a nonredox reaction, the addition of one molecule of water to the C[TRIPLE BOND]C bond of acetylene to form acetaldehyde. Its crystal structure (1.26 Å) reveals a close to octahedral, or trigonal antiprismatic tungsten center, which binds a water molecule that gets activated by an adjacent aspartate residue such that it can attack an acetylene molecule bound in a distinct, hydrophobic pocket. This requires a strong shift of pKa of the aspartate, caused by a nearby low-potential [4Fe–4S] cluster. To gain access to this novel W-Asp-active site, the protein evolved a new substrate channel distant from where it is found in other molybdenum and tungsten enzymes.</dcterms:abstract> <dcterms:issued>2011</dcterms:issued> <dc:contributor>tenBrink, Felix</dc:contributor> <dc:contributor>Abt, Dietmar</dc:contributor> <dspace:isPartOfCollection rdf:resource=""/> <dc:contributor>Einsle, Oliver</dc:contributor> <dc:creator>Seiffert, Grazyna B</dc:creator> <dc:creator>Kroneck, Peter M.
