description:
The structure of the epitope bound by P20.1 Fab was determined by molecular replacement. There are two molecules in the crystallographic asymmetric unit. PDB chains for each complex are: Complex I : Antibody heavy-chain: H, Antibody light-chain: L, epitope chain: P. Complex II : Antibody heavy-chain: I, Antibody light-chain: M, epitope chain: Q. The conformation of the interface residues was almost identical in the two complexes, with minor differences at the periphery. The side chain of H: R53; bends toward the P7 in one of the complexes, acting like a ""lid"". Whereas, in the other complex, it assumes a different conformer, but it still contacts the peptide using its Cbeta.
