应用
N-乙酰基-β-D-氨基葡糖苷酶（NAG）已用作：
- 检测N-乙酰基-β-D-氨基葡糖苷酶（NAG）的底物
- 作为底物研究几丁质酶ChiB1的活性
- 评估大鼠嗜碱性白血病(RBL)-2H3细胞的脱粒情况
生化/生理作用
4-硝基苯基N-乙酰基-β-D-氨基葡糖苷（NP-GlcNAc）是一种广泛使用的己糖苷酶底物。酶作用裂解糖苷键并形成4-酚盐（pNP），测量波长为405 nm。NP-GlcNAc还可结合二乙基氨基乙基-a-环糊精（DEn-CD）使用，用于b-N-乙酰氨基葡萄糖苷酶的快速、准确速率测定方法。环糊精衍生物作为添加剂，在酶的最佳pH值5附近将4-酚盐电离成黄色的4-硝基酚盐。
底物
N-乙酰-氨基葡糖苷酶的发色底物。

Tubulointerstitial damage plays an important role in chronic kidney disease (CKD) with proteinuria. Urinary kidney injury molecule 1 (KIM-1) reflects tubular KIM-1 and is considered a sensitive biomarker for early tubular damage. We hypothesized that a decrease in proteinuria by

We purified a chitinase from pilei extractions of Coprinopsis cinerea fruiting bodies by ammonium sulfate precipitation and CM Sepharose cation exchange chromatography. MALDI-TOF/TOF MS analysis characterized this purified chitinase as a putative class V chitinase, ChiB1. ChiB1 hydrolyzed colloidal chitin

Chemical modification of p-chloromercuribenzoate (PCMB) on beta-N-acetyl-d-glucosaminidase (NAGase, EC 3.2.1.52) from green crab (Scylla serrata) has been studied. The results show that sulfhydryl group is essential for the activity of the enzyme. Inhibitory kinetics of the enzyme by mercuric chloride

We found that the recombinant endo-beta-N-acetylglucosaminidase of Mucor hiemalis (Endo-M) expressed in Candida boidinii had the transglycosylation activity of transferring a bisecting hybrid-type oligosaccharide from an ovalbumin glycopeptide to the acceptor (p-nitrophenyl 2-acetamido-2-deoxy-beta-D-glucopyranoside) in a good yield of 43%.
