1.97.1.9 | tungstate | SER isolated from periplasmic fractions from cells grown on 1 mM tungstate display selenate reductase activities with a 20fold reduction in Vmax and a 23fold increase in substrate binding affinity. The thermo-stability and pH dependence of tungsten-SER is shown to be similar to that observed for molybdenum-SER | Thauera selenatis |
