| 摘要 |
<p>The invention relates to isolated proteases homologous to a protease derived from a strain of Thermoascus aurantiacus and DNA encoding the same. A homologous polypeptide is derived from Aspergillus oryzae. The proteases can be used in animal feed. The Thermoascus protease is a metalloprotease with an HEFTH motif. The optimum temperature is around 70 °C, the optimum pH is around pH6, and the protease is stable over a broad pH range of pH3 to pH10.</p> |
