Abstract

Influence of a homogeneous magnetic field on catalytic rate is proposed as a tool for the investigation of enzyme association. Investigations were initiated with studies of the effect of a 1.4 T homogeneous magnetic field on trypsin activity at 36.5 degrees C and pH 3.3, 5.3, and 7.2, respectively. Periods of exposure were applied up to 2--7 h. No detectable change of activity was observed in any of the exposed systems when they were compared with the identical but unexposed ones.

摘要

提出均匀磁场对催化速率的影响作为研究酶缔合的一种工具。研究始于分别在36.5℃以及pH值为3.3、5.3和7.2的条件下,研究1.4 T均匀磁场对胰蛋白酶活性的影响。暴露时间长达2至7小时。当将任何暴露系统与相同但未暴露的系统进行比较时,未观察到活性有可检测到的变化。
