By contrast, under anaerobic conditions, the reverse reaction becomes spontaneous and organisms such as Micrococcus denitrificans and Thiobacillus denitrificans can reduce nitrate as an energy source.

Denitrification. Nitrogen is returned to its atmospheric form by the action of denitrifying bacteria such as Pseudomonas thiobacillus and Micrococcus denitrificans. The process is known as denitrification and the reaction is as follows ... 

R. palustris has an even more extended 80 s loop. Micrococcus denitrificans C550 and R. capsulata a are remarkably similar molecules, differing by no more than the cytochromes c of spinach and Euglena. In spite of the difference in metabolic roles, respiration vs. photosynthesis, csso seems like a perfectly normal member of the cj class. 

Dissimilatory nitrate reductases (Pichinoty type A) in membrane fractions from bacteria have been shown capable of utilizing a variety of respiratory Intermediates and reduced pyridine nucleotides for nitrate reduction (Cole and Wimpeny, 1968 Knook et ai, 1973 Burke and Lascelles, 1975 Enoch and Lester, 1975). Reduction of nitrate by the membrane fractions, when respiratory substrates or pyridine nucleotides serve as reduc-tant, is generally inhibited by azide, cyanide and p-chloromercuribenzoate. Nitrate reduction, mediated by respiratory substrates, could be inhibited by n-heptylhydroxyquinoline-N oxide (HONO) or dicoumoral (Ruiz-Herrera and DeMoss, 1%9 Knook et al., 1973 Burke and Lascelles, 1975). However, in Micrococcus denitrificans (Lam and Nicholas, 1969) and in Bacillus stearothermophilus (Downey, 1%6) nitrate reduction is not inhibited by...

Little is known of the catalytic properties of cytochrome b investigators must rely on the spectrum characterization of cytochrome b rather than on its enzymic activity to evaluate the purity of the preparation. Little is known of the heme group of mammalian cytochrome b. It is significant that cytochrome b extracted from Micrococcus denitrificans and Pseudomonas denitrificans contains protoheme, the same heme as is in cytochrome c. The nature of the binding between the prosthetic group and the protein is not known. The firm thioester bond in cytochrome c probably is not present in cytochrome b.
