Genome polyprotein - Q01499 (POLG_BVDVS)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

Number of PDB entries for Q01499: 2
Initial binding to target cell probably involves interaction of E(rns) with glycosaminoglycans. E1 and/or E2 are responsible of cell attachment with CD46 and subsequent fusion after internalization of the virion by endocytosis. (data source: UniProt  )
P7 forms a leader sequence to properly orient NS2 in the membrane. (data source: UniProt  )

Uncleaved NS2-3 is required for production of infectious virus. (data source: UniProt  )
NS2 protease seems to play a vital role in viral RNA replication control and in the pathogenicity of the virus. (data source: UniProt  )
NS3 displays three enzymatic activities: serine protease, NTPase and RNA helicase. (data source: UniProt  )
NS4A is a cofactor for the NS3 protease activity. (data source: UniProt  )
RNA-directed RNA polymerase NS5 replicates the viral (+) and (-) genome. (data source: UniProt  )
Subunit structure
The E(rns) glycoprotein is found as a homodimer; disulfide-linked (By similarity). The E1 and E2 envelope glycoproteins form disulfide-linked homodimers as well as heterodimers. (data source: UniProt  )

Data origin/color codes
The vertical color bar on the left side indicates data provenance.
Data in green originates from UniProtKB  
Data in yellow originates from Pfam  , by interacting with the HMMER3 web site  
Data in orange originates from the SCOP   (version 1.75) and SCOPe   (version 2.04) classifications.
Data in grey has been calculated using BioJava  . Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  
  • Red: potentially disorderd region
  • Blue: probably ordered region.
Hydropathy has been calculated using a sliding window of 15 residues and summing up scores from standard hydrophobicity tables.
  • Red: hydrophobic
  • Blue: hydrophilic.
Data in lilac represent the genomic exon structure projected onto the UniProt sequence.
Data in blue originates from PDB
  • Secstruc: Secondary structure projected from representative PDB entries onto the UniProt sequence.
Data in red indicates combined ranges of Homology Models from SBKB   and the Protein Model Portal  

The PDB to UniProt mapping is based on the data provided by the EBI SIFTS project. See also Velankar et al., Nucleic Acids Research 33, D262-265 (2005).
