... such as Paracoccus pantotrophus presents one such challenge since it may result in excessive electron delivery to the respiratory redox chain when compared with the availability of terminal oxidant, O 2 . The level of a periplasmic ubiquinol-dependent nitrate reductase, NAP, is up-regulated in the presence of highly...

...R.S. Zajicek; S.J. Ferguson Paracoccus pantotrophus cytochrome cd 1 nitrite reductase is isolated under aerobic conditions from anaerobically grown cells in an inactive form. This state requires reductive activation to make it catalytically competent for nitrite reduction. In this work, we discuss...
