一般說明
半乳糖氧化酶是一种细胞外含铜酶，由半知菌真菌 树状指孢霉分泌。它可催化一系列伯醇（包括D-半乳糖）氧化成相应的醛，同时将氧还原成过氧化氢。
應用
半乳糖氧化酶可作为一种分析工具，用于特异性测定血浆、植物提取物和磷脂中的D-半乳糖。它可用于表征几种聚合物中的末端D-半乳糖苷单元。
生化／生理作用
半乳糖氧化酶可催化D-半乳糖向D-半乳糖-己二醛的转化。
2-脱氧-D-半乳糖、乳糖、甘露糖、棉子糖和水苏糖可与过氧化物酶：邻甲苯胺系统中的半乳糖氧化酶发生反应。
基本上没有观察到D-葡萄糖、L-半乳糖、L-阿拉伯糖或D-葡萄糖醛酸盐的氧化。

Irinotecan (CPT11), a broad-spectrum cytotoxic anticancer agent, induces a series of toxic side-effects. The most conspicuous side-effect is gastrointestinal mucositis, including nausea, vomiting, and diarrhea. A growing body of evidence indicates that bacteria β-glucuronidase (GUS), an enzyme expressed by intestinal

Galactose oxidase (GOase) was shown to oxidise several C2/C3 fluorinated galactose analogues. Interestingly, the enzyme was able to distinguish between the 2,3-tetrafluorinated galactose and its epimeric glucose analogue, and this represents the first reported biotransformation of a heavily fluorinated sugar.
