3D structures of Coronavirus SARS-CoV-2 proteins and related drugs in HOMCOS server

[Go to Japanese page]

Last Update:20201225, Date for updating PDB:20210210

We summarize 3D structures of proteins in Coronavirus SARS-CoV-2 that causes coronavirus disease 2019 (COVID-19) in a following table.
We provide analyses "Searching Contact Molecules with Query Protein" of HOMCOS for each protein of the virus. Monomeric and bound 3D structures of the virus proteins and their homologs are summarized. Found 3D structures can be used for templates of homology modeling. Details of the usage are explained in the HELP page.
For large proteins with > 1000 amino acids, making the analysis page will take more than 10 seconds.　Please wait for a while.

Proteins in UniProt

Amino acid sequences of SARS-CoV-2 were taken from UniProt pre_release files. They include entries for the SARS-CoV-2 virus (proteome UP000464024) and SARS-CoV virus (proteome UP000000354) and human target proteins. ([HEAD_LINE] [FTP_SITE])
