| 英文摘要 | The effect of theophylline on the immobilized enzyme has been investigated using polyaniline uricase electrode. The activity of the immobilized uricase is markedly inhibited by theophylline. However, this is a reversible inhibition. In the presence of theophylline, the effect of pH on the response current of the enzyme electrode is different from that without theophylline; the response current of the enzyme electrode rapidly increase with increasing potential from 0.20-0.5V, and then increases slowly with further increasing potential. The activation energy of the enzyme-catalyzed reaction is 47.8kJ.mol(-1) in the presence of theophylline, which is much larger than that without theophylline (29.9kJ.mol(-1)). This indicates that the path of the enzyme-catalyzed reaction was changed by theophylline. |
