CoV-2 3CL

Source:Escherichia Coli. Physical Appearance:Filtered White lyophilized (freeze-dried) powder. Biological ActivityCoV-2 3CL is a cysteine protease that cleaves proteins with sequences including LQ (S/A/G) . The cleavage takes c-terminal to the glutamine residue. The SARS CoV-2 3CL protease (C30 Endopeptidase) derived from human SARS-CoV-2 is a C30-type cysteine protease situated in the NS3 segment. SARS CoV-2 3CL protease biological functionality is needed to process viral polyproteins to functional complete units. SARS CoV-2 3CL protease (main protease) is the core protease protein in CoV and corresponds to non-structural protein 5. SARS CoV-2 3CL cleaves the CoV polyprotein at 11 locations. SARS CoV-2 3CL protease has a cysteine-histidine catalytic dyad at its active site and cleaves a Gln– (Ser/Ala/Gly) peptide bond. SARS CoV-2 3CL protease at position P1 cleaves the bond between the glutamine and serine/alanine/glycine. SARS CoV-2 3CL protease is necessary in the processing of the CoV replicase polyprotein. Recombinant Coronavirus 2019 3CL Protease having a Mw of approximately 33.8 kDa was purified from E. coli. The CoV-2 3CL contains 306 amino acids and purified by proprietary chromatographic technique.
