The influenza/H1N1 virus has caused hazard in the public health of many countries. Hence, existing influenza drugs could not cope with H1N1 infection due to the high mutation rate of the virus. In this respect, new method to block the virus was devised. The polymerase pac-pb1n enzyme is responsible for the replication of H1N1 virus. Thus, novel inhibitors were developed to ward off the functionality of the enzyme. In this research, cyclic peptides has been chosen to inhibit PAc-PB1n due to its proven stability in reaching the drug target. Thus, computational method for elucidating the molecular interaction between cyclic peptides …
Ultra-Deep Pyrosequencing Of Partial Surface Protein Genes From Infectious Salmon Anaemia Virus (Isav) Suggest Novel Mechanisms Involved In Transition To Virulence, Torstein Tengs Dr.
Ultra-Deep Pyrosequencing Of Partial Surface Protein Genes From Infectious Salmon Anaemia Virus (Isav) Suggest Novel Mechanisms Involved In Transition To Virulence, Torstein Tengs Dr.
Dr. Torstein Tengs
Uncultivable HPR0 strains of infectious salmon anaemia viruses (ISAVs) infecting gills are non-virulent putative precursors of virulent ISAVs (vISAVs) causing systemic disease in farmed Atlantic salmon (Salmo salar). The transition to virulence involves two molecular events, a deletion in the highly polymorphic region (HPR) of the hemagglutinin-esterase (HE) gene and a Q266→L266 substitution or insertion next to the putative cleavage site (R267) in the fusion protein (F). We have performed ultra-deep pyrosequencing (UDPS) of these gene regions from healthy fish positive for HPR0 virus carrying full-length HPR sampled in a screening program, and a vISAV strain from an ISA outbreak …

Sequence Analysis Of The Genome Of Piscine Orthoreovirus (Prv) Associated With Heart And Skeletal Muscle Inflammation (Hsmi) In Atlantic Salmon (Salmo Salar), Torstein Tengs Dr.

Piscine orthoreovirus (PRV) is associated with heart- and skeletal muscle inflammation (HSMI) of farmed Atlantic salmon (Salmo salar). We have performed detailed sequence analysis of the PRV genome with focus on putative encoded proteins, compared with prototype strains from mammalian (MRV T3D)- and avian orthoreoviruses (ARV-138), and aquareovirus (GCRV-873). Amino acid identities were low for most gene segments but detailed sequence analysis showed that many protein motifs or key amino acid residues known to be central to protein function are conserved for most PRV proteins. For M-class proteins this included a proline residue in μ2 which, for MRV, has been …

A Mobile Genetic Element With Unknown Function Found In Distantly Related Viruses, Torstein Tengs Dr.
Dr. Torstein Tengs
BACKGROUND
The genetic element s2m seems to represent one of very few examples of mobile genetic elements in viruses. The function remains obscure and a scattered taxonomical distribution has been reported by numerous groups.
METHODS
We have searched GenBank in order to identify all viral accessions that have s2m(-like) sequence motifs. Rigorous phylogenetic analyses and constrained tree topology testing were also performed in order to investigate the apparently mobile nature of s2m.
RESULTS
The stem-loop s2m structure can be found in four families of + ssRNA viruses; Astroviridae, Caliciviridae, Picornaviridae and Coronaviridae. In all of these virus families, with the …
