NADH dehydrogenase activity was characterized in the mitochondrial lysates of Phytomonas serpens, a trypanosomatid flagellate parasitizing plants. Two different high molecular weight NADH dehydrogenases were characterized by native PAGE and detected by direct in-gel activity staining. The association of NADH dehydrogenase activities with two distinct multisubunit complexes was revealed in the second dimension performed under denaturing conditions. One subunit present in both complexes cross-reacted with the antibody against the 39 kDa subunit of bovine complex I. Out of several subunits analyzed by MS, one contained a domain characteristic for the LYR family subunit of the NADH:ubiquinone oxidoreductases. Spectrophotometric measurement of the NADH:ubiquinone 10 and NADH:ferricyanide dehydrogenase activities revealed their different sensitivities to rotenone, piericidin, and diphenyl iodonium. |
