Researchers Uncover 3-D Structure Of Virus Replication Technique
...not to frameshift depends on whether thepseudoknot unravels when it collides with the ribosome, Rich said. If it doesnot unravel, the ribosome can slide back one nucleotide and then make a fusionprotein, involving both the structural protein and the polymerase. If thepseudoknot does unravel, then only the s......ace, tugging ona strand of the protein fibronectin unravels a loop critical to cell recognitionbut otherwise leaves the protein intact for reactivation. Reporting in the Feb. 16 issue of the Proceedings of the NationalAcademy of Sciences, researchers at the University of Washington and theUniversity o...
