title: Comparative aspects of adenylic acid deaminase and aspartate-2-oxoglutarate aminotransferase.
abstract: 1. The content of adenylic acid deaminase and of aspartate-2-oxoglutarate aminotransferase of skeletal muscle tissue from a variety of animals has been determined. 2. White (fast) muscle contained large amounts of adenylic acid deaminase and red (slow) muscle contained large amounts of aspartate aminotransferase. There was a general inverse relationship between the adenylic acid deaminase and the aspartate aminotransferase content of muscles from various vertebrates. Thus, there is no simple correlation between the capacity to produce inosinic acid and ammonia from adenylic acid and the capacity to catalyse the formation of aspartate for conversion of inosinic acid back to adenylic acid. 3. The absence of adenylic acid deaminase from the tail muscles of the yabbie and other invertebrates indicates a marked difference in the Animal Kingdom.
