The Genome Sequence of the SARS

We sequenced the 29 751-base genome of the severe acute respiratory syndrome (SARS)–associated coronavirus known as the Tor2 isolate The genome sequence reveals that this coronavirus is only moderately related to other known coronaviruses including two human coronaviruses HCoV-OC43 and HCoV-229E Phylogenetic analysis of the predicted viral proteins indicates that the virus does not

SARS‐CoV‐2 receptor ACE2 and TMPRSS2 are primarily

Coronavirus entry requires its binding to host cell receptor ACE 2 and subsequent priming by TMPRSS 2 Using unpublished single‐cell data of the human lung and bronchia this study reveals expression of potential SARS ‐CoV‐2 cofactors ACE 2 TMPRSS 2 and FURIN primarily in bronchial cells transitioning from secretory to ciliated identity

Functional screen reveals SARS coronavirus nonstructural

Although the final cap structures of viral and cellular mRNAs are similar some RNA viruses adopt unique biochemical mechanisms to build the cap structure (2–4) Coronaviruses are the etiological agents of respiratory and enteric diseases in humans and livestock exemplified by the life-threatening severe acute respiratory syndrome (SARS) caused by SARS coronavirus (SARS-CoV) ( 5 )

Glecaprevir and Maraviroc are high

In a recent study MVC is recommended as a potential drug The crystal structure of SARS-CoV-2 M pro in complex with different inhibitors provide a basis to identify potential inhibitors We have extensively analyzed the available crystal structures of SARS-CoV-2 M pro including the PDB IDs 5R7Y 5R7Z 5R80 5R81 5R83 5R84 5RE4 5RE9 5REB 5RF1 5EFQ 6LU7 and 6W63 and investigated

PRACE Awards Ten Further Projects in Hunt for a COVID

Several projects make the structure and screening results of targets in the virus such as 3CLpro Spike nsp1 RNA-dependent RNA polymerase etc visible clarify their functions and how they can be blocked with various compounds and tools To find all these answers and to make new discoveries scientists need to use different libraries with tens of millions of compounds including ZINK drug

Baloxavir marboxil

Baloxavir marboxil (BXM) sold under the brand name Xofluza is an antiviral medication for treatment of influenza A and influenza B flu It was approved for medical use in Japan and in the United States in 2018 and is TongWein as a single dose by mouth It may reduce the duration of flu symptoms by about a day but is prone to selection of resistant mutants that render it ineffectual

Viruses

The pharmacological reduction of nsp16 2′-O-MTase activity can disrupt the 2′-O-methylation in the RNA cap structure and promote the accumulation of cap-0 structures with lower efficiency of translation thereby suppressing the synthesis of viral proteins while the viral RNA lacking a cap-1 structure can be recognized by innate RNA sensors and stimulate an early type I interferon response

Immunology of COVID

Increasingly studies are being published that provide evidence for the tropism of SARS-CoV-2 to tissues outside the respiratory system – i e the affinity of SARS-CoV-2 to infect organs besides the lungs (Chu et al 2020 Xiao Tang et al 2020) Of note a postmortem study of six patients who died of COVID-19 revealed that the novel coronavirus has the potential to infect the secondary

Structure

Structure-based stabilization of protein–protein interactions (PPIs) is a promising strategy for drug discovery However this approach has mainly focused on the stabilization of native PPIs and non-native PPIs have received little consideration Here we identified a non-native interaction interface on the three-dimensional dimeric structure of the N-terminal domain of the MERS-CoV

Coronaviridae – Wikipedia

Die Coronaviridae umgangssprachlich auch Coronaviren genannt sind eine Virusfamilie innerhalb der Ordnung Nidovirales Ihre Vertreter verursachen bei verschiedenen Wirbeltieren wie Sugetieren Vgeln und Fischen sehr unterschiedliche Erkrankungen Die ersten Coronaviren wurden bereits Mitte der 1960er Jahre beschrieben Coronaviren sind genetisch hochvariabel einzelne Arten aus der

Zinc finger

History Zinc fingers were first identified in a study of transcription in the African clawed frog Xenopus laevis in the laboratory of Klug A study of the transcription of a particular RNA sequence revealed that the binding strength of a small transcription factor (transcription factor IIIA TFIIIA) was due to the presence of zinc-coordinating finger-like structures
