The antibody could combine with Mn porphyrin and showed a haloperoxidase activity. The affinities of the antibody for antigen and Mn porphyrin were 4 98×10 -5 mol/L and 7 63×10 -5 mol/L, respectively. When the antibody-Mn porphyrin complex was used to catalyze the halogenation reaction, the Michaelis constant and reactive rate constant κ cat for H 2O 2 were 5 127 0×10 -3 mol/L and 0 483 4 s -1, respectively. The enzyme exchange number κ cat/K m=94 285 1 mol/(L·s).展开更多
