Abstract

The biochemical properties of the metal ions in a series of nickel enzymes are briefly reviewed. In particular, the properties of urease, hydrogenase, acetyl-CoA synthase/carbon monoxide dehydrogenase, methyl coenzyme-M reductase, superoxide dismutase, and acireductone dioxygenase are discussed in terms of relationships between the structure of the Ni ions in the active site and the molecular mechanism of catalysis.
