in bovine heart mitochondria bongkrekic acid at concentrations as low as about 4 nmol/mg protein ( a ) completely inhibits phosphorylation of exogenous adenosine diphosphate ( adp ) and dephosphorylation of exogenous adenosine triphosphate ( atp ) , ( b ) completely reverses atractyloside inhibition of inner membrane contraction induced by exogenous adenine nucleotides , and ( c ) decreases the amount of adenine nucleotide required to elicit maximal exogenous adenine nucleotide-induced inner membrane contraction to a level which appears to correspond closely with the concentration of contractile , exogenous adenine nucleotide binding sites bongkrekic acid at concentrations greater than 4 nmol/mg protein induces inner membrane contraction which seems to depend on the presence of endogenous adp and/or atp .
