Patent ID: 10202594

Abstract:
The present invention relates to a polypeptide having proline-specific endoprotease activity, wherein the polypeptide has less than 70% residual activity when the polypeptide has been kept at a temperature of 65° C. for 15 min.The invention further relates to a polypeptide having proline-specific endoprotease activity comprising an amino acid sequence according to SEQ ID NO: 1, wherein SEQ ID NO: 1 comprises at least one combination of amino acid substitutions selected from the group consisting of a combination selected from the group consisting of (K238E, I204V, V460A), (F279S, A242V, N507I), (T145A, K424M), (T359A, F379S), (M170I, A421T), (N441S, G484S), (L470H, Q288R), (L470H, E387G), (T281S, L373I), (P304A, P469A), and (P466T, P469Q), a nucleic acid encoding a polypeptide having proline-specific endoprotease activity, a method of making a variant polypeptide having proline-specific endoprotease activity, a recombinant host cell and a method of producing the polypeptide and a process for the preparation of a food or feed product wherein the polypeptide is used.
