Consensus phytases

Abstract

A process for obtaining a consensus protein from a group of amino acid sequences of a defined protein family, proteins and polynucleotides so obtained, and compositions containing such proteins.

1 - 12 . (canceled)  
     
     
         13 . A consensus protein which has the amino acid sequence selected from the group consisting of SEQ ID NO:17 and amino acid sequences containing amino acid additions, deletions, and replacements to SEQ ID NO:17, which sequences have up to two amino acids which are different from the sequence of SEQ ID NO:17.  
     
     
         14 . A consensus protein which has the amino acid sequence selected from the group consisting of SEQ ID NO:15 and amino acid sequences containing amino acid additions, deletions, and replacements to SEQ ID NO:15, which sequences have up to two amino acids which are different from the sequence of SEQ ID NO:15.  
     
     
         15 . A mutein which has the amino acid sequence of SEQ ID NO:17 with the proviso that Q at position 50 is replaced by L, T or G.  
     
     
         16 . A mutein which has the amino acid sequence of SEQ ID NO:17 with the proviso that Q at position 50 is replaced by T and Y at position 51 is replaced by N.  
     
     
         17 . A mutein which has the amino acid sequence of SEQ ID NO:17 with the proviso that Q at position 50 is replaced by L and Y at position 51 is replaced by N.  
     
     
         24 . A polypeptide having the amino acid sequence of SEQ ID NO:15.  
     
     
         25 . A polypeptide having the amino acid sequence of SEQ ID NO:17.  
     
     
         26 . A food composition comprising a foodstuff or feed and an amino acid sequence selected from the group consisting of SEQ ID NO:15 and amino acid sequences containing amino acid additions, deletions, and replacements to SEQ ID NO:15 SEQ ID NO:1, which sequences have up to two amino acids which are different from the sequence of SEQ ID NO:15.  
     
     
         27 . A food composition according to  claim 26  comprising a polypeptide having the amino acid sequence of SEQ ID NO:15.  
     
     
         28 . A food composition comprising a foodstuff or feed and an amino acid sequence selected from the group consisting of SEQ ID NO:17 and amino acid sequences containing amino acid additions, deletions, and replacements to SEQ ID NO:17, which sequences have up to two amino acids which are different from the sequence of SEQ ID NO:17.  
     
     
         29 . A food composition according to  claim 28  comprising a polypeptide having the amino acid sequence of SEQ ID NO:17.
