Analysis of the complexes of the camel antibody heavy chain fragment (cHC) with bovine carbonic anhydrase (bCA) or chicken egg lysozyme (cEL). A, B: The complex structures of the cHC with the bCA (A) or the cEL (B). The cHC, 1G6V:K in A and 1ZVH:A in B, are coloured white. The bCA (1G6V:A in A) and the cEL (1ZVH:L in B) are coded by eight colours. The residues whose CAs are located within 8 Å of the CAs of the antibodies are shown by space fill. C, D: The colour-coded amino acid sequences of the bCA (C) and the cEL (D). The residues shown by space fill in A and B are underlined in C and D, respectively.
