(a) Structure of the combining site of the DB3–progesterone complex,24 showing the main chain of the complementarity determining region (CDR) loops and highlighting contact residues in green (AsnH35, TrpH50, TyrH97, TrpH100, PheH100b, HisL27d and ValL94). (Note, the side-chain of PheH100b is shown but not numbered). (b) Model of the combining site of 1A4, showing the short H3 loop and residues IleH95 and TrpH50. No attempt to model the different light chain has been made.
