Hemagglutinin-Esterase (HE) Dimeric Protein |
| T172 |
49-91 |
Sentence |
denotes |
HE hemagglutinates and destroys receptors. |
| T173 |
92-220 |
Sentence |
denotes |
As RNA viruses, CoVs bear RDEs, which are used in effective attachment to hosts and also reversely in detachment from the hosts. |
| T174 |
221-287 |
Sentence |
denotes |
For example, enveloped RNA viruses evade the hosts via their RDEs. |
| T175 |
288-392 |
Sentence |
denotes |
Currently, RDE-related functional enzymes such as neuraminidase (NA) and SA-O-acetyl-esterase are known. |
| T176 |
393-559 |
Sentence |
denotes |
SA-O-acetyl-esterase was originally identified in influenza C virus and in nidoviruses (CoV and torovirus) as well as in salmon anemia virus (teleost orthomyxovirus). |
| T177 |
560-645 |
Sentence |
denotes |
The origin and evolution of CoV SA-O-acetylesterases are correlated to other viruses. |
| T178 |
646-764 |
Sentence |
denotes |
The fusion event of S glycoprotein and HE is specific for HCoV attachment to SA-associated receptors in the host [25]. |
| T179 |
765-805 |
Sentence |
denotes |
The HE has acetylesterase activity [26]. |
| T180 |
806-915 |
Sentence |
denotes |
In early SA-related biology, influenza A/B viruses were found to recognize chicken erythrocytes in 1942 [27]. |
| T181 |
916-991 |
Sentence |
denotes |
They caused hemagglutination through clumping by virus-borne hemagglutinin. |
| T182 |
992-1105 |
Sentence |
denotes |
These phenomena were widely found in influenza viruses, paramyxoviruses, Newcastle disease (NDV) and mumps virus. |
