title: Preliminary crystallographic studies of an anti-HIV-1 protease antibody that inhibits enzyme activity.
abstract: F11.2.32, a monoclonal antibody directed against the HIV-1 protease, displays strong inhibitory effects toward the catalytic activity of the enzyme. The antibody cross-reacts with peptides 36-46 and 36-57 from the protease. Crystals of the Fab have been obtained both in the free state and as complexes formed with the protease peptide fragments, 36-46 and 36-57. Diffraction data have been collected for the free and complexed forms of Fab F11.2.32 and preliminary models for the crystal structures were obtained by molecular replacement.
