After infecting host cells, the coronaviral ORF1a/b RNA is first translated with the help of host cells into two polyprotein precursors (PP1a and PP1ab) which are then cleaved by Mpro and papain like proteases to produce multiple nonstructural proteins. These nonstructural proteins are involved in the production of viral subgene RNA and four structural proteins (envelope/E protein, membrane/M protein, spike/S protein and nucleocapsid/N protein), which in turn complete the reproduction and release of the progeny virus. Since the Mpro protease plays a vital role in the life cycle of the virus and there is no homologous protein in the human body, the Mpro main protease is an ideal target for developing antiviral drugs. Meanwhile because Mpro is highly conservative among beta coronaviruses, the Mpro inhibitors selected have a broad-spectrum anti-coronavirus ability and may even be used in curing other animal diseases such as porcine coronavirus.Aladdin's 2019-nCoV Main Protease is purified using the PerfectProtein™ Platform developed by aladdin. It is recombinantly expressed in E. coli without any additional tags or amino acids, ensuring complete identity with the natural Main Protease in 2019-nCoV virus.s2019-nCoV inhibitor screening; enzyme activity or structural studiesPhysical AppearanceliquidBiological Activity≥300U/g or 300μmol/min/gUnit DefinitionOne unit is defined as the amount of enzyme that catalyzes the production of 1μmol of MCA-AVLQ per minute at 37℃ under pH7.0.
