摘要:
The present invention relates to the field of genetic engineering, particularly to phytase variant YeAPPA having improved pepsin resistance and acid resistance, and increased catalytic efficiency, by substituting Leucine at the 162th site of the sequence set forth in SEQ ID NO.1 with glycine or proline or substituting glutamic acid at the 230th site of the sequence set forth in SEQ ID NO.1 with glycine, proline or arginine, in the benefit of the development of economical feed enzyme industry.
