1. The sequences of Zika virus protein E. Protein sequences of Zika virus downloaded from UniProt data set. Glycoprotein envelope E is valid and selected. A0A7U3RTL8_Polyprotein and A0A1V0E2F5_Envelope_protein_E encoded the same Glycoprotein envelope. But A0A1V0E2F5 had too many "X" letters, which was not suitable for MEME domain search results. Therefore, we chose A0A7U3RTL8_Polyprotein as the E protein.
