肠道贾第鞭毛虫包囊形成中有半乳糖胺的掺入,而半乳精胺合成的第一步反应是果糖-6-磷酸(F6P)转化成葡糖胺-6-磷酸(GlcN6P)。反应由GlcN6P异构酶(2-氨基-2-脱氧-D-葡糖胺6-磷酸乙酮醇异构酶)催化。作者叙述了利用肠贾第鞭毛虫包囊形成反应对GlcN6P异构酶进行纯化的过程,并首次描述了此酶纯化后的特征。
Enteric giardia cyst formation with galactosamine incorporation, and the first step in the synthesis of galactosamine is fructose-6-phosphate (F6P) into glucosamine-6-phosphate (GlcN6P) . The reaction is catalyzed by GlcN6P isomerase (2-amino-2-deoxy-D-glucosamine 6-phosphate alcohol isomerase). The authors describe the procedure for the purification of GlcN6P isomerase by the giardinosis of Giardia intestinalis and describe for the first time the characteristics of this enzyme after purification.
