We are aiming to switch to the new UniProt website on Monday, May 9. Please explore and share your feedback.
Take me to the new website.
UniProtKB - P03643 (G_BPPHS)
Protein
Major spike protein G
Gene
G
Organism
Enterobacteria phage phiX174 (Isolate Sanger) (Bacteriophage phi-X174)
Status
Functioni
Attaches the circulating virion to the bacterial lipopolysaccharides which serve as receptor for the virus. Determines the phage host-range. Probably triggers with protein H the injection of the phage DNA into the host cytoplasm upon conformational changes induced by the interaction with host lipopolysaccharides.
