Recombinant SARS-CoV-2 ORF1ab Protein, N-His-tagged
Product Description
Cat
IMP-4365
Official Symbol
ORF1ab
Product Overview
Recombinant SARS-CoV-2 (2019-nCoV) 3CL Protease (YP_009725295.1) (Ser3264-Gln3569) was expressed with a N-terminal polyhistidine tagged.
Description
3C-like protease (3CLpro) is the main protease of Humann Coronavirus. 3C-like protease (3CLpro) is a key enzyme, as it cleaves several sites to produce non-structural proteins that are essential for genome replication and Coronavirus virion production, such as an RNA-dependent RNA polymerase, a helicase, ribonucleases and 3CLpro itself, from two types of polyproteins (pp1a and pp1ab). SARS-CoV 3CLpro exists as a homodimer and each protomer has an active site.
