一种高比活木聚糖酶XYN11F63及其基因和应用
摘要：
本发明涉及基因工程领域，具体地，本发明涉及一种高比活木聚糖酶XYN11F63及其基因和应用。本发明提供了一种来源于青霉属Penicillium sp.F63 CGMCC1669的木聚糖酶XYN11F63，其氨基酸序列如SEQ ID NO.1所示，且本发明提供了编码上述木聚糖酶的基因组和cDNA编码基因xyn11F63。本发明的木聚糖酶的具有以下性质：最适pH4.5，最适温度40℃，比活为7988U/mg；极好的蛋白酶抗性以及易于工业化发酵生产。做为一种新型的酶制剂，可广泛用于动物饲料、食品、造纸、能源工业等。
摘要（英）：

The present invention relates to the field of genetic engineering, in particular to high-specific-activity xylanase XYN11F63 and genes and application thereof. The invention provides xylanase XYN11F63 derived from Penicillium sp.F63 (CGMCC No.1669), wherein the amino acid sequences thereof is shown in SEQ ID No.1; and the invention further provides the genome for coding the xylanase and cDNA-coding genesxyn11F63. The xylanase of the invention has the following properties: the optimal pH value thereof is 4.5, the optimal temperature thereof is 40 DEG C, and the specific activity thereof is 7,988U/mg, and the xylanase has good proteinase resistance and is suitable for industrialized fermentation production; and the xylanase is widely applicable as a novel enzymic preparation in the industries of animal feed, food, papermaking, energy and the like.
