摘要
The equilibrium constant for the deamination of aspartic acid to fumaric acid and ammonia has been measured between 5 and 37° with the enzyme aspartase, and between 60 and 135° by the nonenzymatic reaction. The equilibrium constant is given by log KDL = 8.188 - 2315.5/T - 0.01025T. The equilibrium constant for the enzyme reaction, KL, is 2KDL. The pH and ionic strength dependence of this equilibrium were also investigated. © 1968, American Chemical Society. All rights reserved.
