Table 1

Kozak contexts of VP6 AUG codons in BTV. Kozak contexts of AUG codons upstream of ORFX in BTV for the 34 segment 9 sequences which appear to contain the complete 5'UTR. Kozak contexts are assumed to be 'strong' if there is 'G' at +4 and an 'A' or 'G' at -3, 'medium' if one of these is present, and 'weak' if neither are present.
