[https://www.uniprot.org/uniprot/SCAFD_BPPHS SCAFD_BPPHS] Assembles the procapsid by joining twelve 12S pre-assembly complex into a T=1 icosahedral particle, called 108S procapsid. Ten proteins D bind each 12S complex, which are formed by three pentamers of F, G, B protein and a H protein. The scaffolding protein is released from the provirion after genome packaging to form the mature virion.<ref>PMID:15890913</ref> <ref>PMID:159449</ref>

== Publication Abstract from PubMed ==
 +
The three-dimensional structure of bacteriophage phiX174 external scaffolding protein D, prior to its interaction with other structural proteins, has been determined to 3.3 angstroms by X-ray crystallography. The crystals belong to space group P4(1)2(1)2 with a dimer in the asymmetric unit that closely resembles asymmetric dimers observed in the phiX174 procapsid structure. Furthermore, application of the crystallographic 4(1) symmetry operation to one of these dimers generates a tetramer similar to the tetramer in the icosahedral asymmetric unit of the procapsid. These data suggest that both dimers and tetramers of the D protein are true morphogenetic intermediates and can form independently of other proteins involved in procapsid morphogenesis. The crystal structure of the D scaffolding protein thus represents the state of the polypeptide prior to procapsid assembly. Hence, comparison with the procapsid structure provides a rare opportunity to follow the conformational switching events necessary for the construction of complex macromolecular assemblies.
