Fig. 2.

Linear representation of the open reading frames (ORFs) of the RaPV-1 genome (with the molecular mass of the predicted proteins in kilodaltons). Numbers show the nucleotide positions of the start of the ORF (first nucleotide after the last stop codon in the same reading frame) and of the stop codon. For each ORF, the position of the start codon is indicated (arrowhead), except for E4 which does not contain a start codon and therefore hypothetically begins at the first in-frame amino acid. NCR, non-coding region.
