Sequence homology of the viral genome between Toca 511 and the pBA9b vector. (A) Diagram of sequence overlap between the viral genome of Toca 511 and the pBA9b vector. (B) Four GU-rich regions were identified in the psi sequence and 5′-gag in Toca 511 (highlighted), and the first 3 regions were present in the pBA9b vector. The underlined ATG indicates the start codon for the Gag polypeptide. The asterisk indicates where the gag sequence ends in the pBA9b vector.
