ESCHERICHIA COLI DHPR/ACNADH COMPLEX
Overview
E. coli dihydrodipicolinate reductase exhibits unusual nucleotide, specificity, with NADH being kinetically twice as effective as NADPH as a, reductant as evidenced by their relative V/K values. To investigate the, nature of the interactions which determine this specificity, we performed, isothermal titration calorimetry to determine the thermodynamic parameters, of binding and determined the three-dimensional structures of the, corresponding enzyme-nucleotide complexes. The thermodynamic binding, parameters for NADPH and NADH were determined to be Kd = 2.12 microM, delta G degree = -7.81 kcal mol-1, delta H degree = -10.98 kcal mol-1, and, delta S degree = -10.5 cal mol-1 deg-1 and Kd = 0.46 microM, delta G, degree = -8.74 kcal mol-1, delta H degree = -8.93 kcal mol-1, and delta S, ...
