| 摘要 |
Provided are recombinant pentapeptide repeat family proteins comprising at least one mutation of an i-1, i+1, and/or i+2 amino acid residue. Also provided are vectors comprising a nucleic acid sequence encoding the above-described pentapeptide repeat family proteins, protein libraries comprising the above pentapeptide repeat family proteins, and vector libraries comprising the above-described vectors. Additionally provided are methods of identifying a pentapeptide repeat family protein with an assayable phenotype, methods of labeling a nucleic acid-interacting macromolecule, and methods of detecting a nucleic acid-interacting macro-molecule.
