- Аннотация: The molecular environment of the internal ribosome entry site (IRES) element of hepatitis C viral (HCV) RNA in the binary complex with the human 40S ribosomal subunit was studied. To this end, RNA derivatives bearing mild UV-reactive perfluorophenylazide groups at nucleotide G87 in IRES domain II and at nucleotide A296 in the subdomain IIIe loop were used, which were prepared by the RNA complementarily-addressed modification with alkylating oligonucleotide derivatives. None of the RNA derivatives were shown to be crosslinked to the 18S rRNA of the 40S subunit. It was found that the photoreactive group of IRES nucleotide A296 was crosslinked to the 40S subunit S2/S3a, S5, and p40 (SOA) proteins. No protein crosslinking was observed for the RNA derivative containing the same photoreactive group in nucleotide G87. It was concluded that the subdomain IIIe loop of the HCV RNA IRES element in the complex with the 40S subunit is located on the outer subunit surface between the head and the body next to the "beak" near the entrance into the mRNA-binding channel.
