This entry represents the Sulfolobus turreted icosahedral virus (STIV) turret protein third jelly roll domain. The C381 turret protein is a component of the STIV virion vertex complex, which orchestrates virion assembly by coordinating interactions of the membrane and various protein components involved. The turret protein is apposed on the penton base C-terminal jelly-roll ring and forms a pentamer consisting of three consecutive layers of jelly-rolls, with each jelly-roll exhibiting different orientations. The interior of the C381 pentamer harbors two rather large cavities, which exhibit an overall positive electrostatic potential, suggesting that the turrets may act as STIV receptor-binding proteins carrying out recognition and attachment to the host receptors. The turret protein shares similarity with many carbohydrate-binding modules as well as domains involved in protein-protein interactions.

This entry represents a jelly-roll domain present in the major capsid protein from Sulfolobus turreted icosahedral virus 1. The structure of this domain is similar to major capsid protein structures of the eukaryotic Paramecium bursaria Chlorella virus, and the bacteriophage PRD1, and shows a common fold with the mammalian adenovirus [1,2].

This Pfam entry represents the Sulfolobus turreted icosahedral virus (STIV) penton protein second jelly roll domain. STIV is a virus that infects the archaeon Sulfolobus solfataricus and was isolated in acidic hot springs. The virus has a unique architecture based on a pseudo T = 31d capsid symmetry with each icosahedral asymmetric unit consisting of 15 copies of the coat subunit (B345), one copy of the A223 penton base protein, one copy of the C381 turret protein, and one copy of the A55 membrane protein. The pentameric penton base protein is a crucial component of the virus as it forms the vertices of the capsid shell and decorates the penton base structure forming the first floor of the turret. The penton protein contains three different layers, with the N termini forming a 10-stranded beta-pore, the middle layer comprising a canonical viral jelly-roll forming a pentameric ring, and the C-terminal forming a second pentameric ring of jelly-rolls. The virus shares the same coat subunit and penton base protein folds as some eukaryotic and bacterial viruses, suggesting that they derive from a common ancestor predating the divergence of the three kingdoms of life. The conservation of the A223 penton base jelly-roll fold, as well as the B345 double jelly-roll fold, strongly suggests an evolutionary connection for these protein modules among phages, archaeal viruses, and eukaryotic viruses.
