Evidence supporting the identity of beef heart mitochondrial chloroform-released adenosine triphosphatase (ATPase) with coupling factor I.
Highly purified mitochondrial chloroform-released beef heart ATPase had molecular weight 330 000, five bands (alpha, beta, gamma, delta, epsilon) in sodium dodecyl sulfate gel electrophoresis and could restore the oxidative-phosphorylation function of A particles. Maximal inhibition (90%) of the enzyme by N,N'-dicyclohexylcarbodiimide was achieved at a molar ratio of inhibitor to protein of 30 : 1. Chloroform introduced into an aqueous solution of beef heart coupling factor I protected it from cold inactivation.
