NIZN[FE4S4] AND NINI[FE4S4] CLUSTERS IN CLOSED AND OPEN ALPHA SUBUNITS OF ACETYL-COA SYNTHASE/CARBON MONOXIDE DEHYDROGENASE
Overview
The crystal structure of the tetrameric alpha2beta2 acetyl-coenzyme A, synthase/carbon monoxide dehydrogenase from Moorella thermoacetica has, been solved at 1.9 A resolution. Surprisingly, the two alpha subunits, display different (open and closed) conformations. Furthermore, X-ray data, collected from crystals near the absorption edges of several metal ions, indicate that the closed form contains one Zn and one Ni at its active, site metal cluster (A-cluster) in the alpha subunit, whereas the open form, has two Ni ions at the corresponding positions. Alternative metal contents, at the active site have been observed in a recent structure of the same, protein in which A-clusters contained one Cu and one Ni, and in, reconstitution studies of a recombinant apo form of a related acetyl-CoA, ...
