Furthermore, this hypothesis was additionally supported by the identification of the mitochondrial neurotoxin MPTP in the early 1980s, which causes selective DA neuron degeneration by inhibiting mitochondrial respiratory electron transport chain complex I, leading to a parkinsonian syndrome in rodents, primates, and humans [27,28].
in 2000 described a patient harboring a novel heteroplasmic m.5874A-G somatic mutation presenting with exercise intolerance, mild bilateral ptosis, limb weakness, and respiratory chain complex III deficiency, hypnotizing that the phenotype associated with this mutation is similar to cytochrome b deficiency because of a high content of tyrosine in cytochrome b and COX III subunits [10].
Therefore, it will be important to identify regulatory proteins involved in the adjustment of respiratory chain complex organization/activity in response to altered redox state.

We define a chain complex C*(A) concentrated in degrees 0,..., | A| as follows.
For any Lie algebra g over a ring k, the Lie algebra homology of g, written [H.sup.Lie.sub.*](g, k), is the homology of the chain complex [[conjunction].sup.*](g) which was introduced by Chevalley and Eilenberg in [8]; namely,
