Abstract

An anchor library is described. A collection of recombinant vectors having a nucleic acid encoding a displayed peptide sequence is provided. The displayed peptide sequence of each of the vectors comprises X (Y ) X (Y ) X (Y ) X , wherein each X , X , X and X is an amino acid residue and any of X , X , X and X can be the same or different from any one other, wherein each Y , Y and Y is alanine or glycine or a combination of alanine and glycine that is respectively c , c and c amino acid residues long and any of Y , Y and Y if present can be the same or different from any one other, wherein each of c , c and c is 0 to about 20, wherein X and X are each attached to an amino acid residue that flanks the displayed peptide sequence. Preferably, at least about 10 to about 10 permutations of all possible permutations of the displayed peptide sequence are present in the anchor library. Preferably, the library does not contain more than about 10% of displayed peptide sequences different from the first mentioned displayed peptide sequences. Also described are methods of making anchor libraries and methods of using anchor libraries to identify a peptide sequence that binds to a target. Recombinant vectors, filamentous phage, nucleic acid molecules and proteins are also provided.
