Gene names

Name:

Organism

Enterobacteria phage phiX174 (Bacteriophage phi-X174)

Taxonomic identifier

10847 [NCBI]

Taxonomic lineage

Viruses › ssDNA viruses › Microviridae › Microvirus

Virus host

Escherichia coli [TaxID: 562]

Protein attributes

Sequence length	175 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	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. Ref.5 Ref.6
Subunit structure	Pentamerises and interacts with H protein, F and B pentamers to form 12S pre-assembly complex. Joining of twelve 12S complex form the procapsid.
Subcellular location	Virion. Host cytoplasm.
Sequence similarities	Belongs to the microvirus G protein family.
