This entry represent the C-terminal domain of alternative NADH:quinone oxidoreductases known as NDH2 that deliver electrons to the respiratory chain by oxidation of NADH and reduction of quinones but does not pump protons. NDH-2 have particular relevance in yeasts like Saccharomyces cerevisiae and in several prokaryotes, whose respiratory chains are devoid of complex I, in which NDH-2 keep the balance and are the main entry point of electrons into the respiratory chains [2]. NDH2 proteins are found in bacteria, certain plant, fungal and protozoan mitochondria, but not in mammals, they have been used as a drug target for Mycoplasma tuberculosis, Plasmodium falciparum and Toxoplasma gondii [1,3].
This family includes both class I and class II oxidoreductases and also NADH oxidases and peroxidases. This domain is actually a small NADH binding domain within a larger FAD binding domain.
