'''CRYSTAL STRUCTURE OF OUTER SURFACE PROTEIN A OF BORRELIA BURGDORFERI COMPLEXED WITH A MURINE MONOCLONAL ANTIBODY FAB'''<br />


==Overview==
==CRYSTAL STRUCTURE OF OUTER SURFACE PROTEIN A OF BORRELIA BURGDORFERI COMPLEXED WITH A MURINE MONOCLONAL ANTIBODY FAB==
OspA (outer surface protein A) is an abundant immunogenic lipoprotein of, the Lyme disease spirochete Borrelia burgdorferi. The crystal structure of, a soluble recombinant form of OspA was solved in a complex with the Fab, fragment of mouse monoclonal antibody 184.1 and refined to a resolution of, 1.9 A. OspA has a repetitive antiparallel beta topology with an unusual, nonglobular region of "freestanding" sheet connecting globular N- and, C-terminal domains. Arrays of residues with alternating charges are a, predominant feature of the folding pattern in the nonglobular region. The, 184.1 epitope overlaps with a well conserved surface in the N-terminal, domain, and a hydrophobic cavity buried in a positively charged cleft in, the C-terminal domain is a potential binding site for an unknown ligand., An exposed variable region on the C-terminal domain of OspA is predicted, to be an important factor in the worldwide effectiveness of OspA-based, vaccines.

== Publication Abstract from PubMed ==
OspA (outer surface protein A) is an abundant immunogenic lipoprotein of the Lyme disease spirochete Borrelia burgdorferi. The crystal structure of a soluble recombinant form of OspA was solved in a complex with the Fab fragment of mouse monoclonal antibody 184.1 and refined to a resolution of 1.9 A. OspA has a repetitive antiparallel beta topology with an unusual nonglobular region of "freestanding" sheet connecting globular N- and C-terminal domains. Arrays of residues with alternating charges are a predominant feature of the folding pattern in the nonglobular region. The 184.1 epitope overlaps with a well conserved surface in the N-terminal domain, and a hydrophobic cavity buried in a positively charged cleft in the C-terminal domain is a potential binding site for an unknown ligand. An exposed variable region on the C-terminal domain of OspA is predicted to be an important factor in the worldwide effectiveness of OspA-based vaccines.
