Structural highlights

6zig is a 33 chain structure with sequence from Lactococcus virus P2. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:Electron Microscopy, Resolution 42.2Å
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

RBP_BPLP2 Binds to the host phosphopolysaccharides at the onset of infection. Upon activation by calcium, the receptor binding proteins change their conformation, presenting their binding sites to the host, and a channel opens at the bottom of the baseplate for DNA ejection.[1] [2]
