Delivery impact due to the Coronavirus Outbreak

With the COVID-19 outbreak in the world, many flights have been cancelled. In order for the customer to receive the goods properly, we use the FedEx Customized Freight (FCF) of Fedex which demands a higher fee. If the delivery fee is more expensive in your area, we will contact you by mail.

Description

About Nsp3

COVID-19 pandemic is caused by 2019nCoV (SARS-CoV-2) infection. 2019nCoV contains 16 Non-structure protein (Nsp1-Nsp16) that may be drugable targets for antiviral compounds discovery against COVID-19¹.

Nsp3: Nsp3 (200 kDa) is the largest protein encoded by the coronavirus genome (SARS-CoV-2, SARS-CoV, MERS, etc.). Nsp3 is an essential component of the replication and transcription complex. It comprises various domains, the organization of which differs between coronavirus genera, due to duplication or absence of some domains. However, the N-terminal region of the Nsp3 is highly conserved among coronavirus, containing a ubiquitin-like (Ubl) globular fold followed by a flexible, extended acidic-domain (AC domain) rich in glutamic acid (38%). Next to the AC domain is a catalytically active ADP-ribose-1"-phosphatase (ADRP, app-1"-pase) domain (also called macro domain or X domain) thought to play a role during synthesis of viral subgenomic RNAs. SARS Unique Domain (SUD), a domain not yet identified in other coronaviruses from alphacoronavirus and betacoronavirus, follows next. The SUD domain binds oligonucleotides known to form G-quadruplexes. Downstream of the SUD domain is a second Ubl domain and the catalytically active PLpro domain that proteolytically processes the Nsp1/2, Nsp2/3 and Nsp3/4 cleavage sites^1,2.
