Amino acid sequences of CDR loops of ZnOBP-grafted VHH fragments
ZnO-binding peptide is underlined. Numbering of the amino acids of cAbBCII10 VHH follows the Kabat numbering system (20). Amino acids of ZnOBP-grafted VHH are numbered as 1–1 to 1–18 (CDR 1 in VHHZnOBP1), 2–1 to 2–20 (CDR 2 in VHHZnOBP2), and 3–1 to 3–16 (CDR 3 in VHHZnOBP3).
