General annotation (Comments)

Function	The small proteins NS2A, NS4A and NS4B are hydrophobic, suggesting a possible membrane-related function. NS5 may play a role in the viral RNA replication. The NS2B/NS3 protease complex processes the viral polyprotein.
Catalytic activity	Selective hydrolysis of -Xaa-Xaa-|-Yaa- bonds in which each of the Xaa can be either Arg or Lys and Yaa can be either Ser or Ala. Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1).
Subunit structure	NS3 and NS2B form a heterodimer. NS3 is the catalytic subunit, whereas NS2B strongly stimulates the latter By similarity.
Subcellular location	Protein C: Virion Potential. Host membrane; Single-pass membrane protein Potential. Small envelope protein M: Virion Potential. Host membrane; Single-pass membrane protein Potential. Envelope protein E: Virion Potential. Host membrane; Multi-pass membrane protein Potential. Non-structural protein 4A: Host membrane; Single-pass membrane protein Potential. Non-structural protein 4B: Host membrane; Multi-pass membrane protein Potential.
Post-translational modification	Specific enzymatic cleavages in vivo yield mature proteins By similarity.
Miscellaneous	The virion of this virus is a nucleocapsid covered by a lipoprotein envelope. The envelope contains two proteins: the protein M and glycoprotein E. The nucleocapsid is a complex of protein C and mRNA. In immature particles, there are 60 icosaedrally organized trimeric spikes on the surface. Each spike consists of three heterodimers of envelope protein M precursor (prM) and envelope protein E By similarity.
Sequence similarities	Contains 1 helicase ATP-binding domain. Contains 1 helicase C-terminal domain. Contains 1 peptidase S7 domain. Contains 1 RdRp catalytic domain.
