Hydrogenase isoenzymes are also common among the metabolically more versatile bacteria (see Chapter 2). For instance, H2 metabolism and isoenzyme composition in enteric bacteria, including Escherichia coli and Salmonella typhimurium, appear to be differentially regulated under the two modes of anaerobic life, fermentation and anaerobic respiration (Table 3.1). Furthermore, biosynthesis of the individual isoenzymes appears to be controlled at a global level by the quality of the carbon source.

As noted in Section 62.1.9.6, reduction of nitrate may occur by assimilatory or dissimilatory pathways. In the former case, the nitrate produced is reduced further to ammonia, which is incorporated into the cell. In the latter case, nitrate is reduced anaerobically to nitrite, serving as an electron acceptor in the respiration of facultative or a few obligate anaerobic bacteria. The example of Escherichia coli has been considered in Section 62.1.13.4.3. This process is usually terminated at nitrite, which accumulates around the cells, but may proceed further1511 as nitrite-linked respiration in the process of denitrification. 

Among respiring bacteria evidence for an energy-linked transhydrogenase was provided by Murthy and Brodie (60) and by Fisher and Sanadi (61) with membrane fragments from Escherichia coli. A similar but apparently non-energy-linked transhydrogenase was also found in Myco-...

Enhancement of both ATP-driven and respiration-driven transhydrogenase in Escherichia coli by a protein factor was reported by Bragg and Hou (JM). This factor restored both ATPase activity as well as energy-linked transhydrogenase activity in factor-stripped membrane fragments. An energy-transfer factor from rat liver mitochondria was found to exert a similar stimulation on respiration-driven transhydrogenation in Escherichia coli (168).
