Mycobacterium tuberculosis has low nitrate reductase activity during aerobic growth (AG), but shows strong hypoxic induction. Virulent M. bovis has weak activity during AG with no hypoxic induction," scientists in the United States report. "Bacille Calmette-Guerin (BCG) lacks activity in both stages. Transcription of narG of the nitrate reductase enzyme operon was higher in M. tuberculosis than in M. bovis or BCG. Transcription of narK2 encoding the nitrate transporter was induced by hypoxia in M. tuberculosis but not M. bovis or BCG. Insertion of the M. tuberculosis narGHJI...
