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].
Baseplate structural protein Gp10, C-terminal domain
This 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 bind ...
This 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.

This entry represents the C-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 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].

This domain is found in Baseplate wedge protein gp7 from Bacteriophage T4 and similar proteins predominantly found in tailed bacteriophages. 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].
