Abstract

The enzymatic oxidation of mercaptoethanol by purified cysteamine oxygenase has been studied. Products were identified by chromatography as isethinic acid (2-hydroxyethan-sulfinic acid) and isethionic acid. Other features of the reaction, as cofactor requirement, the influence of the enzyme concentration on the stage of oxidation, the biological significance of this reaction are also discussed.

摘要

对纯化的半胱胺氧化酶催化巯基乙醇的酶促氧化反应进行了研究。通过色谱法鉴定产物为羟乙磺酸（2-羟基乙亚磺酸）和羟乙磺酸钠。还讨论了该反应的其他特征，如辅因子需求、酶浓度对氧化阶段的影响以及该反应的生物学意义。
