  • Title: Purification and properties of the F1-ATPase from liver mitochondria of Gallus gallus.
    Author: Lo Piero AR, Petrone G.
    Journal: Comp Biochem Physiol B; 1992 Sep; 103(1):235-8. PubMed ID: 1451435.
    Abstract:
    1. This paper is the first detailed report of the purification of a mitochondrial ATPase from an avian species. 2. The Gallus gallus liver mitochondrial F1-ATPase was purified by chloroform extraction and ion-exchange chromatography. 3. The enzyme shows the five alpha, beta, tau, delta, and epsilon subunits characteristic of mitochondrial F1-ATPases. 4. The Km for ATP is 1 mM and for Mg 0.5 mM with a specific activity of 25.2 mu moles of ATP hydrolyzed x min-1 x mg-1. 5. Unlike mammals enzymes the chicken mitochondrial ATPase shows maximal activity with ITP as substrate, and is strongly inhibited by Cu.
