Primary and secondary structure of black beetle virus RNA2, the genomic messenger for BBV coat protein precursor

摘要: Abstract The nucleotide sequence of black beetle virion (BBV) RNA2 has been determined. is 1399 b long. Its 5' terminus capped. 3' an unidentified moiety that renders the RNA resistent to polyadenylation and ligation. The first AUG codon at base 23 followed by open reading frame for a protein 407 amino acids long, predicted size coat precursor. A second putative 72 acid residues long begins 1110. No other large frames exist. half can be folded into imperfect hairpin high stability. fold complex set multiply bifurcated stem loop regions.
