| PF07553 | Host cell surface-exposed lipoprotein (Lipoprotein_Ltp) | Host cell surface-exposed lipoprotein | This domain is found as 1 to 5 copies in lipoproteins that are involved in superinfection exclusion. Proteins in this group have been shown to act at the stage of DNA release from the phage head into the cell [1]. This domain shows a three-helix bund ... | Domain |
