Human monoclonal antibody 2219 is a neutralizing antibody isolated from a, human immunodeficiency virus type 1-infected individual. 2219 was, originally selected for binding to a V3 fusion protein and can neutralize, primary isolates from subtypes B, A, and F. Thus, 2219 represents a, cross-reactive, human anti-V3 antibody. Fab 2219 binds to one face of the, variable V3 beta-hairpin, primarily contacting conserved residues on the, N-terminal beta-strand of V3, leaving the V3 crown or tip largely, accessible. Three V3/2219 complexes reveal the antibody-bound, conformations for both the N- and C-terminal regions that flank the V3, crown and illustrate how twisting of the V3 loop alters the relative, dispositions and pairing of the amino acids in the adjacent V3, beta-strands and how the antibody can accommodate V3 loops with different, sequences.
