Methanogenic Archaea – Hydrothermal Vent – Early Earth- Evolution of Redox Metabolism – Bioenergy Production - Redox Metabolism of Mycobacteria

Evolution of heme-based systems:

Methane forming strictly anaerobic archaea, called methanogens, were generally considered incapable of metabolizing sulfite and devoid of the respective enzyme called sulfite reductase.  These organisms perform one of the most ancient metabolisms of Earth, hydrogen dependent methanogenesis (4H2 + CO2 à CH4 + 2H2O).  In the 2005-2012 period our laboratory showed that the methanogens that live in deep-sea volcanoes or hydrothermal vents indeed metabolize sulfite and for this purpose, they employ a special enzyme called F420-dependent sulfite reductase (Fsr) (2-4, 10).  The conditions in the hydrothermal vents mimic some aspects of early Earth.  The data indicated that Fsr was probably built in methanogens from certain ancient parts.  Starting from these clues we have carried a bioinformatics based search and found that small heme-containing proteins of a variety of structures representing the essential core of sulfite reductases, is almost universally present in the methanogens, although only rarely a methanogen exhibits sulfite reductase activity (10).  We named these proteins dissimilatory sulfite reductase type protein or Dsr-LP.  It is likely that Dsr-LP carries out a function that was essential to living cells on early Earth. The structural characteristics of the DsrLPs taken together provide a scheme for the evolution of heme-containing sulfite reductases in bacteria, plant, and animal.  Current research in the laboratory hints to the possibility of new heme-based metabolism that began with DsrLPs and could be widespread in the extant living systems.  This exploration has been funded by NASA.

Evolution of thioredoxin based redox control systems:

Thioredoxin or Trx has been known as a master controller of critical metabolisms in a wide variety of living cells and the associated systems have been studied in detail in plants and animals.  Some of the notable examples of Trx-controlled systems are photosynthesis in plant and cell death and aging in humans. The Trx systems have not been studied much in the anaerobic microorganisms some of whom are most ancient inhabitants of Earth.  Our recent bioinformatics and experimental studies indicate that two branches of the Trx system, one being dependent on a nicotinamide coenzyme (NTR) and the other on iron-containing proteins called ferredoxins (FTR), arose independently.  We found that FTR is likely an invention of the ancient bacteria and NTR seemed to have been developed by the early archaea, including methanogens (1) (our unpublished data).  In both cases, the likely early utilities of the Trx systems have been in the control of carbon dioxide fixation and defense against oxidative damage.  The latter aspect became an important metabolism as oxygen appeared on Earth and the original inhabitants, which were accustomed to living without oxygen, had to deal with oxidative stress.  Since the Trx system is an integral part of the cellular redox-control, the new information resulting from our research would have applicability in the production of biofuel and mitigation of greenhouse-gas (methane) emission and provide new leads for research on plant and animal metabolism.  This research has been supported by a grant from the NSF and involves the following collaborators: Bob. B. Buchanan, University of California, Berkeley, CA; Ruth Schmitz-Streit, Christian-Albrechts-Universität Kiel, Kiel, Germany; Mónica Balsera, Instituto de Recursos Naturales y Agrobiología de Salamanca (IRNASA-CSIC), Salamanca, Spain; Peter Schürmann, Laboratoire de Biologie Moléculaire et Cellulaire, Rue Emile Argand 11, Neuchâtel, Switzerland;

Development of therapeutics and vaccine for tuberculosis:

In this research, we are collaborators of Endang Purwantini of the Department of Biochemistry, Virginia Tech. Coenzyme F420 is an essential component of the methanogenic archaea and rarely found in bacteria and absent in humans.  Mycobacteria, which includes Mycobacterium tuberculosis, the causative agent of tuberculosis or TB, are the rare group of bacteria that carry F420 (5-7).  The ongoing research by us and others indicates that it plays could play a critical role in TB pathogenesis.  We have shown in M. tuberculosis could use the reduced form of coenzyme F420 to neutralize nitrosative stress imposed by the human host and this process could act as a sensor for the immunological competence of the host (8).   More recently, we have found that some of the coenzyme F420-dependent proteins help to build the resilient cell wall of M. tuberculosis, and they could occur on the cell surface (9).  Consequently, these proteins are attractive targets for the development of TB vaccines and drugs.  To capitalize on this opportunity we have developed a collaboration with the PT Bio Farma, an Indonesian company producing international quality vaccines that are used worldwide, including the USA.  The research on mycobacteria has been funded by an NIH grant
