Comments
This protein (Swiss-prot;P14336) is genome polyprotein from Tick-borne encephalitis virus, which is composed of capsid protein C, matrix protein, major envelope protein E, four non-structural proteins, flavivirin (EC 3.4.21.91), RNA-directed RNA polymerase (EC 2.7.7.48).
However, the catalytic domain of these enzymes have not been determined yet. (The PDB structure (1svb) corresponds to major envelope protein E.)
