Gp7 provides the primary control of the conformational changes of the viral baseplate during assembly and infection. This protein is organised into six domains connected by flexible linkers.

Gp7 provides the primary control of the conformational changes of the viral baseplate during assembly and infection. This protein is organised into six domains connected by flexible linkers. This entry represents Domain V, which is an insertion into domain IV and consists of an eight-stranded beta- barrel followed by two short alpha-helices [1].

Gp7 provides the primary control of the conformational changes of the viral baseplate during assembly and infection. This protein is organised into six domains connected by flexible linkers. This entry represents Domain VI, which forms a ribbon-like structure that interacts with N-terminal region of the protein Gp10 [1].

PF07880Bacteriophage T4 gp9/10-like protein, N-terminal (T4_gp9_10_N)Bacteriophage T4 gp9/10-like protein, N-terminalThis entry represents the N-terminal domain of Baseplate protein gp9 from Bacteriophage T4, a component of the viral baseplate [1]. Gp9 connects the long tail fibres of the virus to the baseplate and triggers tail contraction after viral attachment t ...This entry represents the N-terminal domain of Baseplate protein gp9 from Bacteriophage T4, a component of the viral baseplate [1]. Gp9 connects the long tail fibres of the virus to the baseplate and triggers tail contraction after viral attachment to a host cell. The protein is active as a trimer, with each monomer being composed of three domains. The N-terminal domain consists of an extended polypeptide chain and two alpha helices. The alpha1 helix from each of the three monomers in the trimer interacts with its counterparts to form a coiled-coil structure. The middle domain is a seven-stranded beta-sandwich. This entry represents the region including these two domains. Noticeably, the long flexible region between N-terminal and middle domains may be required for the function of gp9 to transmit signals from the long tail fibres [2]. Together with gp11, gp10 initiates the assembly of wedges that then go on to associate with a hub to form the viral baseplate [1].

PF21939Baseplate structural protein Gp10, C-terminal domain (Gp10_C)Baseplate structural protein Gp10, C-terminal domainThis entry represents the C-terminal domain (CTD) of baseplate structural protein Gp10 that assembles into trimeric structures.

The core structure and assembly of Gp10 has structural similarity to that of the head domain of Gp11 and the receptor binding domain of Gp12 [1]. The monomeric CTD of Gp10 consists of an alpha-helix followed by a three-stranded, antiparallel beta-sheet, which is almost perpendicular to the helix. The three symmetry related beta-sheets interact with their first beta-strands in the trimer, thus creating a flower-like arrangement with the alpha-helices being the flower stem and the three beta-sheets being the petals.

Gp9 connects the long tail fibres of the virus to the baseplate and triggers tail contraction after viral attachment to a host cell. The protein is active as a trimer, with each monomer being composed of three domains. The C-terminal domain is thought to be essential for trimerisation and is organised into an eight- stranded antiparallel beta-barrel, which was found to resemble the 'jelly roll' fold found in many viral capsid proteins [2]. Together with gp11, gp10 initiates the assembly of wedges that then go on to associate with a hub to form the viral baseplate [1].

Most of the family appear to be phage tail proteins; however some appear to be involved in other processes. For instance Swiss:Q03314 from Rhizobium leguminosarum may be involved in plant-microbe interactions ([1]). A related protein Swiss:Q9L3N1 is involved in the pathogenicity of Microcystis aeruginosa. The finding of this family in a structural component of the phage tail fibre baseplate (Swiss:P10930) suggests that its function is structural rather than enzymatic. Structural studies show this region consists of a helix and a loop ([2]) and three beta-strands. This alignment does not catch the third strand as it is separated from the rest of the structure by around 100 residues. This strand is conserved in homologues but the intervening sequence is not. Much of the function of Swiss:P10930 appears to reside in this intervening region. In the tertiary structure of the phage baseplate this domain forms part of the 'collar'. The domain may bind SO4, however the residues accredited with this vary between the PDB file and the Swiss-Prot entry. The long unconserved region maybe due to domain swapping in and out of a loop or reflective of rapid evolution.

PF14928Short tail fibre protein receptor-binding domain (S_tail_recep_bd)Short tail fibre protein receptor-binding domainThis domain is a receptor binding domain found on bacteriophage short tail fibre proteins.
