Historically, research on RNA helicase and translocation enzymes has seemed like a footnote to the extraordinary progress in studies on DNA-remodeling enzymes. However, during the past decade, the rising wave of activity in RNA science has engendered intense interest in the behaviors of specialized motor enzymes that remodel RNA molecules. Functional, mechanistic, and structural investigations of these RNA enzymes have begun to reveal the molecular basis for their key roles in RNA metabolism and signaling. In this chapter, we highlight the structural and mechanistic similarities among monomeric RNA translo-case enzymes, while emphasizing the many divergent characteristics that have caused this enzyme family to become one of the most important in metabolism and gene expression.

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious 24 disease localized to China, Japan, and Korea that is characterized by severe hemorrhage and a 25 high fatality rate. Currently, no specific vaccine or treatment has been approved for this 26 disease. To develop a therapeutic agent for SFTS, we isolated antibodies from a phage-27 displayed antibody library that was constructed from a patient who recovered from SFTS 28 virus (SFTSV) infection. One antibody, designated as Ab10, was reactive to the Gn envelope 29 glycoprotein of SFTSV and protected host cells and A129 mice from infection in both in 30 vitro and in vivo experiments. Notably, Ab10 protected 80% of mice, even when injected 5 31 days after inoculation with a lethal dose of SFTSV. Using cross-linker assisted mass 32 spectrometry and alanine scanning, we located the non-linear epitope of Ab10 on the Gn 33 glycoprotein domain II and an unstructured stem region, suggesting that Ab10 may inhibit a 34 conformational alteration that is critical for cell membrane fusion between the virus and host 35 cell. Ab10 reacted to recombinant Gn glycoprotein in Gangwon/Korea/2012, HB28, and SD4 36 strains. Additionally, based on its epitope, we predict that Ab10 binds the Gn glycoprotein in 37 247 of 272 reported SFTSV isolates previously reported. Together, these data suggest that 38 Ab10 has potential to be developed into a therapeutic agent that could protect against more 39 than 90% of reported SFTSV isolates. 40 41

While dromedaries are the immediate animal source of Middle East Respiratory Syndrome (MERS) epidemic, viruses related to MERS coronavirus (MERS-CoV) have also been found in bats as well as hedgehogs. To elucidate the evolution of MERS-CoV-related viruses and their interspecies transmission pathway, samples were collected from different mammals in China. A novel coronavirus related to MERS-CoV, Erinaceus amurensis hedgehog coronavirus HKU31 (Ea-HedCoV HKU31), was identified from two Amur hedgehogs. Genome analysis supported that Ea-HedCoV HKU31 represents a novel species under Merbecovirus, being most closely related to Erinaceus CoV from European hedgehogs in Germany, with 79.6% genome sequence identity. Compared to other members of Merbecovirus, Ea-HedCoV HKU31 possessed unique non-structural proteins and putative cleavage sites at ORF1ab. Phylogenetic analysis showed that Ea-HedCoV HKU31 and BetaCoV Erinaceus/VMC/DEU/2012 were closely related to NeoCoV and BatCoV PREDICT from African bats in the spike region, suggesting that the latter bat viruses have arisen from recombination between CoVs from hedgehogs and bats. The predicted HKU31 receptor-binding domain (RBD) possessed only one out of 12 critical amino acid residues for binding to human dipeptidyl peptidase 4 (hDPP4), the MERS-CoV receptor. The structural modeling of the HKU31-RBD-hDPP4 binding interphase compared to that of MERS-CoV and Tylonycteris bat CoV HKU4 (Ty-BatCoV HKU4) suggested that HKU31-RBD is unlikely to bind to hDPP4. Our findings support that hedgehogs are an important reservoir of Merbecovirus, with evidence of recombination with viruses from bats. Further investigations in bats, hedgehogs and related animals are warranted to understand the evolution of MERS-CoV-related viruses.
