Structure of the N-glycan attached to the chlorovirus PBCV-1 major capsid protein (Vp54). Monosaccharides (Man and Araf) connected by dashed lines are non-stoichiometric substituents. The larger black box encloses the conserved pentasaccharide core structure common to all chloroviruses analyzed to date. The inner red box indicates the tetrasaccharide structure of the N-glycan of the antigenic mutant chlorovirus PIL6 [6].
