Mikrobiyol Bul. 2015 Jul;49(3):414-22. doi: 10.5578/mb.9247.

Coronaviruses (CoV) are enveloped, spherical, single-stranded positive-sense RNA viruses causing mainly respiratory and intestinal infections in animals and humans. Until recently five types of human coronaviruses (HCoV-OC43, HCoV-HKU1, HCoV-NL63, HCoV-229E, SARS-CoV) have been known, however a novel CoV has...

Nat Microbiol. 2016 May;1(5). doi: 10.1038/nmicrobiol.2016.29. Epub 2016 Mar 21.

RNA-dependent RNA polymerases (RdRps) are used by RNA viruses to replicate and transcribe their RNA genomes1. They adopt a closed, right-handed fold with conserved subdomains called palm, fingers, and thumb1,2. Conserved RdRp motifs A-F coordinate the viral RNA template,...

Reprint of "Modeling the intracellular replication of influenza A virus in the presence of defective interfering RNAs.

Virus research

Laske T, Heldt FS, Hoffmann H, Frensing T, Reichl U.
PMID: 27208847
Virus Res. 2016 Jun 15;218:86-95. doi: 10.1016/j.virusres.2016.05.009.

Like many other viral pathogens, influenza A viruses can form defective interfering particles (DIPs). These particles carry a large internal deletion in at least one of their genome segments. Thus, their replication depends on the co-infection of cells by...

Phosphocholine conjugation: an unexpected in vivo conjugation pathway associated with hepatitis c ns5b inhibitors featuring a bicyclo[1.1.1]pentane.

Drug metabolism and disposition: the biological fate of chemicals

Zhuo X, Cantone JL, Wang Y, Leet JE, Drexler DM, Yeung KS, Huang XS, Eastman KJ, Parcella KE, Mosure KW, Soars MG, Kadow JF, Johnson BM.
PMID: 26961241
Drug Metab Dispos. 2016 Aug;44(8):1332-1340. doi: 10.1124/dmd.115.069062. Epub 2016 Mar 09.

During a medicinal chemistry campaign to identify inhibitors of the hepatitis C virus nonstructural protein 5B (RNA-dependent RNA polymerase), a bicyclo[1.1.1]pentane was introduced into the chemical scaffold to improve metabolic stability. The inhibitors bearing this feature, 5-(3-(bicyclo[1.1.1]pentan-1-ylcarbamoyl)-4-fluorophenyl)-2-(4-fluorophenyl)-N-methyl-6-(3,3,3-trifluoropropyl)furo[2,3-b]pyridine-3-carboxamide (1) and...

Identification of Novel Inhibitors for Tobacco Mosaic Virus Infection in Solanaceae Plants.

Advances in bioinformatics

Prabahar A, Swaminathan S, Loganathan A, Jegadeesan R.

Adv Bioinformatics. 2015;2015:198214. doi: 10.1155/2015/198214. Epub 2015 Oct 18.

Tobacco mosaic virus (TMV) infects several crops of economic importance (e.g., tomato) and remains as one of the major concerns to the farmers. TMV enters the host cell and produces the capping enzyme RNA polymerase. The viral genome replicates...

6K2-induced vesicles can move cell to cell during turnip mosaic virus infection.

Frontiers in microbiology

Grangeon R, Jiang J, Wan J, Agbeci M, Zheng H, Laliberté JF.
PMID: 24409170
Front Microbiol. 2013 Dec 04;4:351. doi: 10.3389/fmicb.2013.00351. eCollection 2013.

To successfully infect plants, viruses replicate in an initially infected cell and then move to neighboring cells through plasmodesmata (PDs). However, the nature of the viral entity that crosses over the cell barrier into non-infected ones is not clear....

Intron gain by tandem genomic duplication: a novel case in a potato gene encoding RNA-dependent RNA polymerase.

PeerJ

Ma MY, Lan XR, Niu DK.
PMID: 27547574
PeerJ. 2016 Jul 26;4:e2272. doi: 10.7717/peerj.2272. eCollection 2016.

The origin and subsequent accumulation of spliceosomal introns are prominent events in the evolution of eukaryotic gene structure. However, the mechanisms underlying intron gain remain unclear because there are few proven cases of recently gained introns. In an RNA-dependent...

Structure-guided design of small-molecule therapeutics against RSV disease.

Expert opinion on drug discovery

Cox R, Plemper RK.

Expert Opin Drug Discov. 2016;11(6):543-556. doi: 10.1517/17460441.2016.1174212. Epub 2016 Apr 21.

INTRODUCTION: In the United States, respiratory syncytial virus (RSV) is responsible for the majority of infant hospitalizations resulting from viral infections, as well as a leading source of pneumonia and bronchiolitis in young children and the elderly. In the...

Polycistronic Expression of the Influenza A Virus RNA-Dependent RNA Polymerase by Using the Thosea asigna Virus 2A-Like Self-Processing Sequence.

Front Microbiol. 2016 Mar 08;7:288. doi: 10.3389/fmicb.2016.00288. eCollection 2016.

The RNA-dependent RNA polymerase (RdRp) of influenza A virus consists of three subunits, PB2, PB1, and PA, and catalyses both viral RNA genome replication and transcription. Cotransfection of four monocistronic expression vectors for these subunits and nucleoprotein with an...
