English: Schematic representation of a myovirus contractile tail. The tail of myoviruses infecting both Gram-positive and Gram-negative hosts harbor conserved proteins that are represented in this scheme. The complete baseplate wedge structure (formed by three types of proteins) is highlighted in red on the right side of the scheme. The table on the right gives the gene product correspondences for each baseplate protein between the two reference phages infecting Escherichia coli (T4 and Mu) and the Listeria monocytogenes phage A511.
TMP: Tape Measure Protein; BW: Baseplate Wedge protein; BH: Baseplate Hub protein; BS: Baseplate Spike; RBP: Receptor Binding Protein; TF: Tail Fiber; MTP: Major Tail Protein.
