Application
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。
Biochem/physiol Actions
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。
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。
对半乳糖和其他糖的特异性与Avigad所描述的相似。
General description
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。
Other Notes
在pH6.0、25℃条件下，一个单位可在过氧化物酶和邻联甲苯胺系统中每分钟产生δ A425=1.0。反应体积=3.4mL，光路= 1cm。

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

Antifreeze glycoproteins (AFGPs) are able to bind to ice, halt its growth, and are the most potent inhibitors of ice recrystallization known. The structural basis for AFGP's unique properties remains largely elusive. Here we determined the antifreeze activities of AFGP

The site-specific modification of proteins is expected to be an important capability for the synthesis of bioconjugates in the future. However, the traditional repertoire of reactions available for the direct modification of proteins suffers from lack of specificity, necessitating costly
