This database is dedicated to the nuclear genes specifying the enzymes, structural proteins, and other proteins, many still not identified, involved in mitochondrial biogenesis and function.

Mitochondrial research, especially the genetics of filamentous fungi. Includes information describing mitochondrial genomes, mutants, extrachromosomal plasmids, and nuclear genes involved in mitochondrial function.

Genome database of polymorphisms and mutations of the human mitochondrial DNA .

Features a cross-referenced list of single nucleotide substitutions in the two hypervariable segments of the mtDNA control region.
