Bacteriophage tail attachment protein FII (IPR008018)

Short name: Phage_tail_attach_FII

Family relationships



The phage head-tail attachment protein is required for the joining of phage heads and tails at the last step of morphogenesis [PMID: 12083526]. FII is incorporated into the base vertex of DNA-filled heads to facilitate head-tail joining and may determine the specificity of tail attachment. There are 5-6 copies of protein FII per mature phage.
