Abstract
Cyanovirin-N (CV-N), an 11-kDa protein from the cyanobacterium Nostoc ellipsosporum, is a highly potent virucidal agent that has generated interest as a lead natural product for the prevention and chemotherapy of human immunodeficiency virus infection. The antiviral activity of CV-N is mediated through specific, high-affinity interactions with the viral surface envelope glycoproteins. A number of structures of wild-type, mutant and sequence-shuffled CV-N have been solved by nuclear magnetic resonance and crystallography, showing that the protein exists as either a quasi-symmetric two-domain monomer or a domain-swapped dimer. Structures of several complexes of CV-N with oligosaccharides help in explaining the unique mode of high-affinity binding of these molecules to both forms of CV-N.
