3foh

Fitting of gp18M crystal structure into 3D cryo-EM reconstruction of bacteriophage T4 extended tail

Loading... Status: waiting for Mol* initialization Structural highlights 3foh is a 6 chain structure with sequence from Escherichia virus T4. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Method: Electron Microscopy, Resolution 15Å Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function TSP_BPT4 Structural component of the bacteriophage tail which consists of a contractile sheath, a tube and a baseplate. The central cylindrical segment of the tail consists of a rigid tube, composed of multiple copies of gp19, surrounded by the outer contractile sheath assembled from gp18 subunits. A total of 138 copies of gp18 arranged into 23 hexameric rings constitutes the sheath. During infection, contraction of the sheath drives the central tube through the host outer membrane, creating a channel for DNA ejection from the capsid into the host cell. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
