INFLUENZA VIRUS HEMAGGLUTININ COMPLEXED WITH A NEUTRALIZING ANTIBODY
Overview
The structure of the hemagglutinin (HA) of a mutant influenza virus that escapes neutralization by a monoclonal antibody shows that the mutation causes changes in HA structure which avoid an energetically less favorable conformation. However, the structure of the mutant HA.Fab complex indicates that the antibody binds selectively to mutant HA in a wild type-like distorted conformation. The association of an antibody with a less favored HA conformation represents an alternative to previously described mechanisms of escape from neutralization by antibodies.
About this Structure
2VIR is a Protein complex structure of sequences from Mus musculus and Unidentified influenza virus. This structure supersedes the now removed PDB entry 1vir. The following page contains interesting information on the relation of 2VIR with [Hemagglutinin]. Full crystallographic information is available from OCA.
