摘要: The present invention provides metal ion affinity peptides, fusion proteins comprising and polynucleotides encoding the proteins. A feature of subject is that peptide has a formula selected from group consisting of: 1: (His-X 1 -X 2 ) n1 -(His-X 3 4 5 n2 6 n3 , wherein each X independently an amino acid with aliphatic or amide side chain, basic chain (except His) acidic are 1–3, 1–5; 2: (His-Asn) n where n=3 to 10; 3: having 10. further recombinant vectors polynucleotides, host cells vectors. methods kits for purifying protein peptide.
