  • Title: Modification of the kinetic parameters of chicken liver cytoplasmic aspartate aminotransferase by lactate dehydrogenase.
    Author: Busquets M, Cortés A, Bozal J.
    Journal: Int J Biochem; 1985; 17(7):825-9. PubMed ID: 4054424.
    Abstract:
    A method for the purification of chicken liver soluble aspartate aminotransferase, lactate dehydrogenase free, is proposed. The preparation, which contained a mixture of the five molecular forms of the enzyme, showed a 120-fold increase in specific activity, with respect to the initial homogenates. Differences in Km(2-oxoglutarate) and saturating concentrations among solutions of purified enzyme and soluble fraction were due to the 2-oxoglutarate reductase activity of lactate dehydrogenase.
