cord-305591-ir3wz6nr	Ji, Danyang	Discovery of G-quadruplex-forming sequences in SARS-CoV-2	2020-06-01		.txt	text/plain	5138	315	55	We have analyzed and identified 25 four contiguous GG runs (G(2)N(x)G(2)N(y)G(2)N(z)G(2)) in the SARS-CoV-2 RNA genome, suggesting putative G-quadruplex-forming sequences (PQSs). We confirm Gquadruplex structure forming in the top-ranked PQSs by multiple spectroscopic assays in vitro and characterize the crosstalk between G-quadruplexes and viral helicase by microscale thermophoresis (MST) and molecular docking. Our analysis of Gquadruplex-forming sequences in SARS-CoV-2 provides insights into the design of anti-viral treatment by targeting the viral helicase and G-quadruplex structures. Interestingly, PQSs at positions 13385 and 24268 with the highest G-scores indicating high probability to adopt G-quadruplex structures only share high sequence similarity to the bat CoVs (see Supplementary Information S1 available online at https://academic.oup.com/bib and Table 2 ). In comparison, our G-quadruplex search across the genome of SARS-CoV-2 also identified a number of GG PQSs. PQS at position 13385 was confirmed to adopt G-quadruplex structures, which also contains a [GAAAG] sequence in the middle ( Table 1 ).	./cache/cord-305591-ir3wz6nr.txt	./txt/cord-305591-ir3wz6nr.txt
