---|---|---|
NS1 | A 46kDa glycoprotein. At the start of the infection process, interacts with NS4A and NS4B transmembrane proteins. |
(De Clercq, 2009; de Sousa Wu et al., 2015; Dhar Dwivedi et al., 2020) |
NS2A | A hydrophobic transmembrane protein with 22-kDa and 218 amino acids. The N-terminal contains 68 amino acids in the lumen of the ER whereas the C-terminal located at the cytoplasm contains 10 amino acids. |
(Egloff Benarroch et al., 2002; Dwivedi et al., 2016; Dražić et al., 2020) |
NS2B | A co-factor to NS3 protease. A hydrophobic protein with 15-kDa (130 amino acids). |
|
NS3 | ~69kDa multifunctional enzyme acts protease RNA triphosphatase and helicase. |
(Oliveira Silva et al., 2014) |
NS4A | ~16kDa; highly hydrophilic on the end of its C-terminus. Suitable as a signal for translocating NS4B to ER lumen. | (Idrees and Ashfaq, 2012) |
NS4B | Consists of 248 amino acids. Small integral membrane protein with high hydrophobicity. |
(Xie Zou et al., 2015) |
NS5 | 104kDa, largest NS protein. Bi-functional enzyme; N-terminal is the domain of methyltransferase and C-terminal is the polymerase RNA dependent on the RNA. |
