the enzyme catalyzes sulfite oxidation using Nitro-blue tetrazolium as artificial electron acceptor at pH 7.8 and 60°C. The enzyme specifically oxidizes sulfite but can work in the reverse direction, reduction of sulfur or tetrathionate, using reduced methyl viologen (MV) as electron donor, thiosulfate is not able to act as an electron acceptor from MV, absence of reduction of thiosulfate by SoeABC. Oxidation of sodium tetrathionate by SoeABC is performed using DCPIP (2,6-dichlorophenolindophenol) in the presence or absence of phenazine methosulfate (PMS). No oxidation of sulfite, tetrathionate, polysulfide or thiosulfate, SoeABC seems therefore to oxidize sulfite specifically |
