The left arm of the Bxb1 genome is represented by a white ruler (tick marks indicate every 100 bp and 1 kbp) with genes shown above as boxes. Individual genes are color-coded to structural components (the capsid protein is shown in light blue for hexon subunits and darker blue for penton subunits). Genes detected by mass spectrometry but not in the cryo-EM density are black, and genes whose products are absent in the virion are gray.
