Sarbecoviruses initiate infection by binding to receptors on host cells via the viral spike surface glycoprotein. The entry receptor for SARS-CoV-1 and SARS-CoV-2 is the human cellsurface protein angiotensin converting enzyme 2 (ACE2), and the receptor binding domain (RBD) of spike from both these viruses binds ACE2 with high affinity (Hoffmann et al., 2020; Letko et al., 2020; Li et al., 2003; Walls et al., 2020; Wrapp et al., 2020a) . Because of its key role in viral entry, the RBD is a major determinant of cross-species transmission and evolution (Becker et al., 2008; Frieman et al., 2012; Letko et al., 2020; Li, 2008; Li et al., 2005b; Qu et al., 2005; Ren et al., 2008; Sheahan et al., 2008a Sheahan et al., , 2008b;; Wu et al., 2012) . In addition, the RBD is the target of the most potent anti-SARS-CoV-2 neutralizing antibodies identified to date (Cao et al., 2020; Ju et al., 2020; Pinto et al., 2020; Rogers et al., 2020; Seydoux et al., 2020; Shi et al., 2020; \n  [tt:M8nnp5OldWX1j5LdL_Rsll2qnmoCwRp64AAcZeKfqKI] Engineered ACE2 receptor therapy overcomes mutational escape of SARS-CoV-2.\n    oronavirus disease 2019 (COVID-19) has spread across the world as a tremendous pandemic and presented an unprecedented challenge to human society. The causative agent of COVID-19, SARS-CoV-2 is a single-stranded positivestrand RNA virus that belongs to lineage B, clade 1 of the betacoronavirus genus [1] [2] [3] . The virus binds to host cells through its trimeric spike glycoprotein composed of two subunits; S1 is responsible for receptor binding and S2 for membrane fusion 4 . Angiotensin-converting enzyme 2 (ACE2) is lineage B clade 1 specific receptor including SARS-CoV-2 3 . The receptor binding domain (RBD) of S1 subunit directly binds ACE2, therefore, it is the most important targeting site to inhibit viral infection. In fact, the RBD is the common binding site of effective neutralizing antibodies identified from convalescent patients [5] [6] [7] . Among RNA viruses, coronaviruses uniquely encode viral RNA proofreading exoribonuclease that may have benefit to large ~30 kb genome 8 . However, SARS-CoV-2 still have high mutation rates ~1 \u00d7 10 -3 substitutions per site per year 9 , which are correlated with high evolvability including the acquisition of anti-viral drug resistance.\n  [tt:5Av3q_Yyc2jvYadPTn2w3vgwMPBgyaT4N27DtBCwiSc] Coronaviruses with a SARS-CoV-2-like receptor-binding domain allowing ACE2-mediated entry into human cells isolated from bats of Indochinese peninsula\n    The origin of SARS-CoV-2, as its mode of introduction into the human population, is currently unknown. Since its emergence, numerous animal species have been studied to identify possible reservoirs and/or intermediate hosts of the virus, including a large diversity of insectivorous bats of the genus Rhinolophus. Despite the recent report of various SARS-CoV-2-related viruses in Rhinolophus shameli (isolated in Cambodia in 2010 1 ), R. pusillus and R. malayanus (China, 2020 and 2019 respectively 2 ), in R. acuminatus (Thailand, 2020 3 ) and R. cornutus (Japan, 2013 4 ), the closest SARS-CoV-2 bat-borne genome still remains the one from R. a nis, RaTG13 (China, 2013) 5, 6 . Several studies also suggested the role of pangolin-related coronaviruses in the emergence of SARS-CoV-2 [7] [8] [9] . Since its appearance in humans, SARS-CoV-2 has evolved only through sporadic mutations, some of which correspond to gains in tness allowing the virus to spread more widely, or to escape neutralizing antibodies 13 . To decipher the origin of SARS-CoV-2, it is therefore essential to ascertain the diversity of animal coronaviruses and more speci cally of bat coronaviruses.

It doesn't seem to directly support a laboratory origin argument.\n\n2. \"Engineered ACE2 receptor therapy overcomes mutational escape of SARS-CoV-2\" - This paper discusses the structure of SARS-CoV-2 and mentions its mutation rates.

I have 3 reads left, and I need to be selective in choosing papers that would support a laboratory origin argument.\n\nLet me first analyze what I've already read:\n\n1. \"Deep mutational scanning of SARS-CoV-2 receptor binding domain reveals constraints on folding and ACE2 binding\" - This paper discusses the natural evolution of sarbecoviruses in bat reservoirs and how they spill over into other species. It doesn't seem to directly support a laboratory origin argument.\n\n2. \"Engineered ACE2 receptor therapy overcomes mutational escape of SARS-CoV-2\" - This paper discusses the structure of SARS-CoV-2 and mentions its mutation rates. It doesn't appear to directly support a laboratory origin argument either.\n\n3. \"Coronaviruses with a SARS-CoV-2-like receptor-binding domain allowing ACE2-mediated entry into human cells isolated from bats of Indochinese peninsula\" - This paper discusses finding SARS-CoV-2-like viruses in bats, which actually supports a natural origin rather than a laboratory origin.\n\nNone of the papers I've read so far directly support a laboratory origin argument. I need to carefully select papers from the remaining list that might contain evidence supporting a laboratory origin.\n\nLooking at the remaining papers, I need to identify ones that might contain information supporting a laboratory origin.
