| Type: | Domain | Name: | Bacteriophage P22 tailspike, N-terminal |
| Description: | The tailspike protein of Salmonella bacteriophage P22 is a viral adhesion protein that mediates attachment of the viral protein to host cell-surface lipopolysaccharide. The tailspike protein displays both receptor binding and destroying properties, inactivating the receptor by endoglycosidase activity. The N-terminal, head-binding domain mediates the non-covalent attachment of the six homotrimeric tailspike molecules to the DNA injection apparatus []. The N-terminal domain of the P22 tailspike protein shows significant sequence similarity to the N-terminal domain of the Shigella phage Sf6 tailspike protein []. | Short Name: | P22_tailspike_N |
