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。
单位定义
一个酶活性单位是指在37 °C、pH 5.5下，每分钟从壳聚糖中释放1.0 μmole还原糖（以D-葡萄糖胺当量计）所需的酶量。

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.

Illumination with white linearly polarized light (WLPL) stimulated chitinase and chitosanase in their degradation of chitin and chitosan, respectively. Enzymes were illuminated at room temperature in separate vessels, then admixed in reactors containing polysaccharides. Hydrolysis of chitosan to glucosamine followed
