Popis: 1. 1. The ATP:citrate lyase from swine adipose tissue can be assayed using conditions to produce either linear or biphasic double-reciprocal plots of citrate saturation curves; the former had lesser velocity than the latter. 2. 2. The ionic forms of the substrate were probably Mg·ATP 2− and either Mg·citrate − or citrate 3− . There was little effect of ATP 4− and inhibition by high Mg 2+ concentrations. 3. 3. The enzyme was inhibited by hydroxycitrate and by ADP, both probably as the magnesium complexes. 4. 4. The ionic form of the inhibitor, tricarballylate, was uncertain.
