Analysis of compound heterozygous and homozygous mutations found in peripheral subunits of human respiratory Complex I, NDUFS1, NDUFS2, NDUFS8 and NDUFV1, by modeling in the E. coli enzyme.

Abstract excerpt

Respiratory Complex I (NADH:ubiquinone oxidoreductase) is composed of 45 subunits, seven mitochondrially-encoded and 38 imported. Mutations in the nuclearly-encoded subunits have been regularly discovered in humans in recent years, and many lead to cardiomyopathy, Leigh Syndrome, and early death. From the literature, we have identified mutations at 17 different sites and constructed 31 mutants in a bacterial...
