title: Isolation and characterization of the ND2 polypeptide of the bovine energy-transducing NADH-ubiquinone oxidoreductase (complex I).
abstract: The M(r) 30,000 polypeptide of the hydrophobic protein fraction of the energy-transducing NADH-ubiquinone oxidoreductase (complex I) of bovine heart mitochondria was identified as the ND2 gene product based on a comparison of amino acid analysis and partial N-terminal sequencing results with the known DNA sequence of ND2 (Anderson, S. et al. (1982) J. Mol. Biol. 156, 683-717). A simple purification procedure was devised for this ND2 gene product. The procedure, which is described, involves treatment of bovine complex I with a chloroform-methanol (2:1 [v/v]) solution. The antiserum raised against this purified bovine ND2 gene product cross-reacted with the approximately M(r) 39,000 polypeptide extracted from the Paracoccus denitrificans membranes with chloroform-methanol (2:1 [v/v]).
