PG - 1929-36 AB - Biological copper-sulfur entities display versatile and unusual coordination chemistry. The role of the sulfur ligation is briefly reviewed through examples from selected copper enzymes and relevant biomimetic models. Copper thiolate complexes are of particular interest because of their key roles in a number of ubiquitous metalloenzymes such as Type I (blue copper proteins) or in the binuclear Cu(A) electrons transfer site found in both cytochrome c oxidase (CcO) and nitrous oxide reductase (N2OR). The possible roles of the S(Met) ligand in monoxygenases are described in relation to recently proposed pathways. Some prospective regarding the biological relevance of disulfide copper ligation and possible radical copper bonds in catalytic cycle are also discussed.
