≥15 units/mg protein (E1%)
浓度
≥0.5 mg/mL
溶解性
0.1 M acetate buffer, pH 5.5: soluble
储存温度
−20°C
应用
Sigma的壳聚糖酶已用于几丁质和壳聚糖的偏振光刺激的酶促水解。
生化/生理作用
壳聚糖酶催化壳聚糖中D-氨基葡萄糖（GlcN-GlcN）残基之间的β-1,4-键的内水解。据报道，来自链霉菌属的酶还能水解部分乙酰化壳聚糖中的GlcNAc-GlcN键。

Canthaxanthin is a reddish-orange xanthophyll with strong antioxidant activity and higher bioavailability than carotenes, primarily used in food, cosmetics, aquaculture, and pharmaceutical industries. The spiking market for natural canthaxanthin promoted researchers toward genetic engineering of heterologous hosts for canthaxanthin production.
