Figure 1.
Figure 1. Crystal structure of Fab F-22-30. (a) Final electron density map (contoured at 1.2 ) of a segment from the H3 hypervariable loop (Ser105H-Trp109H). (b) Molecular surface of the antibody recombination site. The positions of some hypervariable loops are indicated. Note a deep pocket delimited by the L1, L3, and H3 hypervariable loops. (c) A difference Fourier (F[o] - F[c]) map contoured at 3 suggests that an unidentified molecule binds to this pocket in the crystal.
