一种褐藻胶裂解酶、其制备方法及应用
摘要：
本发明涉及基因工程技术领域，尤其涉及一种褐藻胶裂解酶、其制备方法及应用，所述褐藻裂解酶的成熟蛋白包含如SEQ ID NO.1所示的氨基酸序列，其前体蛋白包含如SEQ ID NO.4所示的氨基酸序列。所述褐藻裂解酶性质稳定，比酶活高达4600U/mL以上，可将褐藻胶酶解为具有特殊生物学活性的小分子褐藻寡糖，具备工业应用的潜质。
摘要（英）：

The invention relates to the field of genetic engineering technology, especially to alginate lyase and a preparation method and application thereof. Maturation protein of the alginate lyase contains an amino acid sequence as shown in the SEQ ID NO. 1, and the precursor protein contains an amino acid sequence as shown in the SEQ ID NO.4. The alginate lyase has stable properties, and specific enzyme activity reaches up to 4600 U/mL and above. Alginate can be subjected to enzymolysis to obtain micromolecular alginate-derived oligosaccharides with special biological activity. The product has the potential for industrial application.
