11. This genome is composed of 7691 nucleotides and encodes and polyprotein of 2250 amino acids. 12. It is predicted to have a polyprotein that can be cleaved into 10 smaller proteins. 13. The Env polyprotein encodes the surface glycoprotein ( SU ) and transmembrane glycoprotein ( TM ). 14. HIV p6 is a 6 kDa polypeptide at the N-terminus of the Gag polyprotein . 15. The tobacco etch virus encodes its entire genome as a single massive polyprotein ( 350 kDa ). 16. It is an analogue of the phenylalanine-proline cleavage site of the HIV Gag-polyprotein . 17. The viral genome consists of 10, 893 nucleotides and encodes a polyprotein of 3384 amino acids. 18. Coronaviruses usually express pp1a ( the ORF1a polyprotein ) and the PP1ab polyprotein with joins ORF1a and ORF1b. 19. Coronaviruses usually express pp1a ( the ORF1a polyprotein ) and the PP1ab polyprotein with joins ORF1a and ORF1b. 20. The RNA genome is replicated and a long polyprotein is formed, where all of the proteins are attached.
