Kinetic mechanism of bovine liver argininosuccinate lyase. Academic Article uri icon

abstract

  • The kinetic mechanism of bovine liver argininosuccinate lyase has been determined at pH 7.5, 25 degrees C. Fumarate and arginine are both noncompetitive inhibitors versus argininosuccinate. The dead-end inhibitor, succinate, is competitive versus fumarate and argininosuccinate, but noncompetitive versus arginine. Citrulline is competitive versus arginine and noncompetitive versus argininosuccinate and fumarate. The results are consistent with a random mechanism with the formation of two dead-end complexes: E . argininosuccinate . fumarate and E . argininosuccinate . arginine. No evidence was obtained for nonlinear reciprocal plots. The equilibrium constant was found to be 3.7 mM.
