Table 1 Position of the open reading frames of PePV.

From: Avian papillomaviruses: the parrot Psittacus erithacus papillomavirus (PePV) genome has a unique organization of the early protein region and is phylogenetically related to the chaffinch papillomavirus

  1. 1 Number of bases from the first base of the ORF until the last base of the last codon before the stop codon. 2 Number of amino acids which would produce the predicted proteins if translation starts at the first ATG of the ORF, except for E4 which does not have a start codon and therefore hypothetically begins at the first in-frame amino acid. 3 Predicted molecular weight (in kilodaltons) of the putative protein.
