T3 |
179-427 |
Sentence |
denotes |
The initial cases of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) occurred in Wuhan, China, in December 2019 and swept the world by 23 June 2020 with 8 993 659 active cases, 469 587 deaths across 216 countries, areas or territories. |
T4 |

Sentence |
denotes |

Sentence |
denotes |
However, the initial source's transmission routes of SARS-CoV-2 remain obscure and controversial. |
T6 |
607-706 |
Sentence |
denotes |
Research data suggest bat (RaTG13) and pangolin carried CoV were the proximal source of SARS-CoV-2. |
T7 |
707-860 |
Sentence |
denotes |
In this study, we used systematic phylogenetic analysis of Coronavirinae subfamily along with wild type human SARS-CoV, MERS-CoV, and SARS-CoV-2 strains. |
T8 |
861-949 |
Sentence |
denotes |
The key residues of the receptor-binding domain (RBD) and O-linked glycan were compared. |
T9 |
950-1125 |
Sentence |
denotes |
SARS-CoV-2 strains were clustered with RaTG13 (97.41% identity), Pangolin-CoV (92.22% identity) and Bat-SL-CoV (80.36% identity), forms a new clade-2 in lineage B of beta-CoV. |
T10 |
1126-1183 |
Sentence |
denotes |
The alignments of RBD contact residues to ACE2 justified? |
T11 |
1184-1302 |
Sentence |
denotes |
Those SARS-CoV-2 strains sequences were 100% identical by each other, significantly varied in RaTG13 and pangolin-CoV. |
T12 |
1303-1422 |
Sentence |
denotes |
SARS-CoV-2 has a polybasic cleavage site with an inserted sequence of PRRA compared to RaTG13 and only PRR to pangolin. |
T13 |
1423-1644 |
Sentence |
denotes |
Only serine (Ser) in pangolin and both threonine (Thr) and serine (Ser) O-linked glycans were seen in RaTG13, suggesting that a detailed study needed in pangolin (Manis javanica) and bat (Rhinolophus affinis) related CoV. |
