Structural highlights

1vd0 is a 1 chain structure with sequence from Escherichia virus Lambda. Full experimental information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:Solution NMR
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT, TOPSAN

Function

DECO_LAMBD Stabilizes the expansion of the capsid head shell after genome packaging. The packaging of viral genome in the procapsid triggers a dramatic reconfiguration of the capsid shell, expanding from roughly 50nm to 60nm while the capsid thickness decreases. 415 capsid decoration protein molecules cooperatively bind the expanded capsid, thereby stabilizing the mature capsid shell.[1] [2] [3]

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
