Hell's Tails: Localizing The Tail Proteins Of The Hyperthermophile-Infecting Virus Ssv1, Jane Arterberry
Hell's Tails: Localizing The Tail Proteins Of The Hyperthermophile-Infecting Virus Ssv1, Jane Arterberry
University Honors Theses
The tail of Saccharolobus spindle-shaped virus 1 (SSV1) has long been thought to be composed solely of viral protein 4 (VP4), but recent SSV1 structural studies have implicated the presence of additional structural proteins C166 and B78 in SSV1's unique tail. The exact locations of these proteins have not been confirmed. Structural proteins VP4 (C-terminus) and B78 are hypothesized to contribute to an adapter region bridging the viral capsid to the tail, whereas C166 is thought to comprise the majority of an internal extended structure, respectively. SSV1 structural proteins lack cysteine residues providing targets to determine their locations in the …

SSV1, spindle-shaped virus 1, is an archaeal virus with a unique shape that belongs to the family of fuselloviruses and infects hyperthermophilic archaea that thrive at 80°C and pH 3. SSV1 has two capsid proteins, VP1 and VP3, that presumably produce the lemon-shaped virion structure characteristic of fuselloviruses. The VP1 amino acid sequence is highly conserved among SSVs. Here, we investigate the importance of the proteolytic cleavage site in position E66 in VP1 by changing its glutamic acid to the other 19 amino acids. We have developed a new protocol for creating SSV1 mutants through HiFi Assembly (NEB) to increase …
