title: Amino acid sequence of the oligomycin sensitivity-conferring protein (OSCP) of beef-heart mitochondria and its homology with the delta-subunit of the F1-ATPase of Escherichia coli.
abstract: The complete amino acid sequence of the oligomycin sensitivity-conferring protein (OSCP) of beef-heart mitochondria is reported. The protein contains 190 amino acids and has a molecular mass of 20 967. Its structure is characterized by a concentration of charged amino acids in the two terminal segments (N 1-77 and C 128-190) of the protein, whereas its central region is more hydrophobic. The earlier reported homology of the protein with the delta-subunit of E. coli F1, based on the terminal amino acid sequences of OSCP, is further substantiated.
