摘要

"Polipeptu00ecdeo, sequence of nucleic acid isolation, construction of expression vector of recombinant nucleic acid, and recombinant host cell, method for producing a polipeptu00ecdeo, CEPAUse of at least a protease, a method to improve the nutritional value of animal feed additive for animal feed, composition of feed, and,Method for the treatment of proteu00ecnas plants ". 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 protease can be used in animal feed. The Thermoascus protease is a metaloprotease with a reason hefth.The optimum temperature is around 70 198 C, the pH optimum around pH 6, and the protease that is stable in a wide pH range from pH 3 to pH 10.
