Function

[DCMB_MOOTH] The beta subunit (this protein) generates CO from CO(2), while the alpha subunit combines the CO with CoA and a methyl group to form acetyl-CoA. The methyl group, which is incorporated into acetyl-CoA, is transferred to the alpha subunit by a corrinoid iron-sulfur protein. [DCMA_MOOTH] The beta subunit generates CO from CO(2), while the alpha subunit (this protein) combines the CO with CoA and a methyl group to form acetyl-CoA. The methyl group, which is incorporated into acetyl-CoA, is transferred to the alpha subunit by a corrinoid iron-sulfur protein.

Publication Abstract from PubMed

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 synthase. On the basis of our observations along with previously reported data, we postulate that only the A-clusters containing two Ni ions are catalytically active.
