Table 5. Comparison of the amino acid residues of E protein between Zhejiang strains, SA14-14-2 and Beijing-1 strain.

Strain	Genotype	Amino acid residue of E protein
		E107	E138	E176	E177	E264	E279	E315	E439
SA14-14-2	III	F	K	V	A	H	M	V	R
Beijing-1	III	L	E	I	T	Q	K	A	K
ZJ82-2	III	L	E	I	T	Q	K	A	K
ZJ14-10	I	L	E	I	T	Q	K	A	K

Note: Only two Japanese encephalitis virus strains obtained in Zhejiang are listed in the table because all Zhejiang strains with the same genotype share identical amino acids in these selected residues. A one-letter code is used for amino acid designation.
