WebJul 15, 2024 · In contrast to the membrane-bound respiratory nitrate reductase (NAR), which lacks nitrite-oxidizing activity, physiological studies have shown that NXRs can catalyse both nitrite oxidation and ... WebHowever, the mRNA level for narX, a putative ‘fused nitrate reductase’ not found in other bacteria, was strongly up-regulated in anaerobic dormant bacilli. narX is the first transcriptionally induced gene in anaerobic dormant mycobacteria and might be a useful marker for monitoring the dormancy response in infected animals.
