Water molecules in the antibody-antigen interface of the structure of the Fab HyHEL-5-lysozyme complex at 1.7 A resolution: comparison with results from isothermal titration calorimetry.
G.H.Cohen, E.W.Silverton, E.A.Padlan, F.Dyda, J.A.Wibbenmeyer, R.C.Willson, D.R.Davies.
The structure of the complex between hen egg-white lysozyme and the Fab HyHEL-5 at 2.7 A resolution has previously been reported [Cohen et al. (1996), Acta Cryst. D52, 315-326]. With the availability of recombinant Fab, the X-ray structure of the complex has been re-evaluated at 1.7 A resolution. The refined structure has yielded a detailed picture of the Fab-lysozyme interface, showing the high complementarity of the protein surfaces as well as several water molecules within the interface that complete the good fit. The model of the full complex has improved significantly, yielding an R(work) of 19.5%. With this model, the structural results can be compared with the results of isothermal titration calorimetry. An attempt has been made to estimate the changes in bound waters that accompany complex formation and the difficulties inherent in using the crystal structures to provide the information necessary to make this calculation are discussed.

Figure 1.
Figure 1 Detailed view of the interactions between seven residues involved in the contacts between the bound lysozyme and the HyHEL-5 antibody. Two residues from lysozyme are shown with blue bonds, two residues from the antibody light chain are shown with yellow bonds and three residues from the heavy chain are shown with green bonds. Hydrogen bonding is shown with thin black bonds. The electron density from a 2F[o] - F[c] map is contoured at 1.8 [sigma] . The diagram was prepared with Ribbons v.3.12 (Carson, 1997 [Carson, M. (1997). Methods Enzymol. 277, 493-505.]-[bluearr.gif] ).

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
