Stable coordination of the inhibitory Ca2+ ion at the metal ion-dependent adhesion site in integrin CD11b/CD18 by an antibody-derived ligand aspartate: implications for integrin regulation and structure-based drug design.

| description: |
The epitope residues were calculated from [PDB: 3Q3G] as the antigen residues at 4 Å
atomic distance from the antibody. [PDB: 3QA3] gives identical epitopes.
The epitope of Fab 107 on the high affinity (open) form of the (Ile316Gly)CD11b A domain was determined from the crystal structure of the complex. The Ile316Gly mutation generates a constitutively active integrin. Each of the four molecules in the asymmetric unit of the complex contains a Ca2+ ion in the metal ion-dependent adhesion site (MIDAS), stabilized by Asp 107 from the Fab 107 heavy chain variable region.
