aMV+-NR and bMV+-Nir activities are expressed as nmol NO2
- produced or consumed · mg protein-1 · min-1. Nor activity is expressed as nmol NO consumed · mg protein-1 · min-1. All of the activities were determined after incubation for 18 h. The data are expressed as the means with the standard error in parentheses from at least two different cultures assayed in triplicate. -, not determined; n.d., not detectable.
