monoclonal anti-lysozyme antibody D1. 3 and the antigen, hen egg white lysozyme, has
been refined by crystallographic techniques using x-ray intensity data to 2.5-A resolution.
The antibody contacts the antigen with residues from all its complementarity determining
regions. Antigen residues 18-27 and 117-125 form a discontinuous antigenic determinant
making hydrogen bonds and van der Waals interactions with the antibody. Water molecules …
