| Short Name | AioB/IdrB_ssu |
| description | This entry represents a group of prokaryotic molybdopterin-containing oxidoreductases, including Arsenite oxidase subunit AioB from Alcaligenes faecalis and Iodate reductase subunit IdrB from Pseudomonas sp. AioB is the small subunit of an arsenite oxidase complex. It is a Rieske protein and appears to rely on the Tat (twin-arginine translocation) system to cross the membrane. Although this enzyme could run in the direction of arsenate reduction to arsenite in principle, the relevant biological function is arsenite oxidation for energy metabolism, not arsenic resistance [, ]. IdrB, a Rieske-type protein with a [2Fe-2S]-binding motif, is involved in iodate respiration [, ]. |
