Major spike protein G (IPR003515)

Short name: Spike_G

Overlapping homologous superfamilies

Family relationships



This is a family of proteins from single-stranded DNA bacteriophages. The G protein is a major spike protein involved in attachment to the bacterial host cell. The virion is composed of sixty copies of each of the F, G and J proteins, and 12 copies of the H protein. There are twelve spikes formed by five G proteins, each a tight beta barrel, and one H protein [PMID: 10739948, PMID: 14553915].
