Human Hepatitis B protein capsid. The complete virion is enveloped in an outer lipid envelope not visible here. Causes Hepatitis B, and possibly cirrhosis and hepatocellular carcinoma, and may be a risk factor for pancreatic cancer. Not visible inside is the not fully double-stranded circular DNA. Rendering is colored by radial depth-cue to highlight surface topography. View is along the 2-fold icosahedral symmetry axis. Individual small spheres are atoms making up the proteins.
