CC   -!- FUNCTION: Completely wraps the viral circular dsDNA genome to form a
CC       nucleoprotein filament (PubMed:31636205). These interactions between
CC       the viral genome and the nucleocapsid proteins probably maintain the
CC       DNA in A-form (Probable). This certainly protects the viral DNA under
CC       conditions such as the extreme desiccation of its host (Probable).
