We don't have any Reviewed sequence in Uniprot and no tertiary structure available for any of the protein of this Virus. How we can work on protein level?
As of UniProt release 2016_03, a Zika virus reference proteome has been manually curated in UniProtKB (http://www.uniprot.org/uniprot/Q32ZE1).
A page dedicated to Zika has also been created in ViralZone to offer a global view of how this particular virus functions and provides access to other databases (http://viralzone.expasy.org/all_by_species/6756.html)
