What's a GeneRIF?

In the current investigation the relationship between ROS production and MMP was studied in respiring yeast cells in stationary phase, using diphenyleneiodonium chloride (DPI), an inhibitor of flavin-containing proteins, as well as the mutants deleted for NDE1, NDE2 and NDI1 genes, encoding flavin-containing external and internal NADH dehydrogenases.

Ubiquinone binding site of yeast NADH dehydrogenase Ndi1 has been described.

Ndi1 assimilates electrons to the electron transport chain and initiates the respiration process to make ATP, whereas under stresses, it cleaves the toxicity-sequestering N-terminal cap, is released from the mitochondria, and becomes a cell killer.

Title: The yeast complex I equivalent NADH dehydrogenase rescues pink1 mutants.
Perfusion of TAT-Ndi1 before 30 min no-flow ischemia and up to 2 hr reperfusion suppressed ROS production and preserved ATP stores. Importantly, TAT-Ndi1 infused before ischemia reduced infarct size by 62%.

the Ndi1 reaction proceeds through a ternary complex (not a ping-pong) mechanism. The bound UQ keeps oxygen away from the reduced flavin.

Yeast NDI1 expression in Drosophila mitigated the aging associated decline in respiratory capacity and the accompanying increase in mitochondrial reactive oxygen species production, and resulted in decreased accumulation of markers of oxidative damage.

report that expression of Ndi1 in fly mitochondria leads to an increase in NADH-ubiquinone oxidoreductase activity, oxygen consumption, and ATP levels.

NP_013586.1

EC 1.6.5.9

NADH:ubiquinone oxidoreductase; transfers electrons from NADH to ubiquinone in respiratory chain but does not pump protons, in contrast to higher eukaryotic multisubunit respiratory complex I; upon apoptotic stress, is activated in mitochondria by N-terminal cleavage, then translocates to cytoplasm to induce apoptosis; homolog of human AIFM2; yeast NDI1 complements several phenotypes of human cell line with mutated MT-ND4, implicated in Leber hereditary optic neuropathy
