Tetrathionate reductase of Salmonella thyphimurium: a molybdenum containing enzyme. 1986

M Hinojosa-Leon, and M Dubourdieu, and J A Sanchez-Crispin, and M Chippaux

Use of radioactive molybdenum demonstrates that the tetrathionate reductase of Salmonella typhimurium is a molydenum containing enzyme. It is proposed that this enzyme shares with other molybdo-proteins, such as nitrate reductase, a common molybdenum containing cofactor the defect of which leads to the loss of the tetrathionate reductase and nitrate reductase activities.

UI MeSH Term Description Entries
D008982 Molybdenum A metallic element with the atomic symbol Mo, atomic number 42, and atomic weight 95.95. It is an essential trace element, being a component of the enzymes xanthine oxidase, aldehyde oxidase, and nitrate reductase. Molybdenum-98,Molybdenum 98
D009565 Nitrate Reductases Oxidoreductases that are specific for the reduction of NITRATES. Reductases, Nitrate
D010088 Oxidoreductases The class of all enzymes catalyzing oxidoreduction reactions. The substrate that is oxidized is regarded as a hydrogen donor. The systematic name is based on donor:acceptor oxidoreductase. The recommended name will be dehydrogenase, wherever this is possible; as an alternative, reductase can be used. Oxidase is only used in cases where O2 is the acceptor. (Enzyme Nomenclature, 1992, p9) Dehydrogenases,Oxidases,Oxidoreductase,Reductases,Dehydrogenase,Oxidase,Reductase
D011868 Radioisotopes Isotopes that exhibit radioactivity and undergo radioactive decay.
