Abstract

The unusual ability of Thiosphaera pantotropha to catalyze respiratory nitrate reduction under aerobic conditions is shown to correlate with the activity of a periplasmic nitrate reductase that is expressed under both aerobic and anaerobic growth conditions. The organism also synthesizes, but only under anaerobic conditions, a membrane-bound nitrate reductase which resembles the corresponding enzyme in Paracoccus denitrificans in respect of both catalytic properties and inhibition of activity in intact cells in the presence of oxygen.
