Nitrite reductase V (nirV) from Pseudomonas stutzeri JM300
This gene is part of the nir operon from P. stutzeri JM300. Nir is the second enzyme of the denitrification pathway, converting nitrite (NO2-) into nitric oxide (NO). NirK nitrite reductases are copper-dependent . It has long been thought the presence of NirS (a heme-dependent Nir) and NirK was mutually exclusive, however, this is not true as for example Pseudomonas stutzeri possesses both . In contrast to NirS, NirK does not need any other genes for its maturation or for it to be functionally active. Nevertheless, in some organisms, e.g. P. stutzeri JM300, nirK gene is accompanied by nirV gene. The exact function of nirV is not elucidated yet as of today [3,4], but it is recognized as a known accessory gene of NirK .
