HUMAN HEPATITIS B VIRAL CAPSID (HBCAG)
Overview
Hepatitis B is a small enveloped DNA virus that poses a major hazard to, human health. The crystal structure of the T = 4 capsid has been solved at, 3.3 A resolution, revealing a largely helical protein fold that is unusual, for icosahedral viruses. The monomer fold is stabilized by a hydrophobic, core that is highly conserved among human viral variants. Association of, two amphipathic alpha-helical hairpins results in formation of a dimer, with a four-helix bundle as the major central feature. The capsid is, assembled from dimers via interactions involving a highly conserved region, near the C terminus of the truncated protein used for crystallization. The, major immunodominant region lies at the tips of the alpha-helical hairpins, that form spikes on the capsid surface.
