1.9.6.1 nitrate + ferrocytochrome Escherichia coli K-12 periplasmic nitrate reductase is expressed under nitrate-limiting conditions. NapG and NapH form a quinol dehydrogenase that couples electron transfer from the high midpoint redox potential ubiquinone-ubiquinol couple via cytochrome NapC and NapB to NapA nitrite + ferricytochrome + H2O
