Product Description

Recombinant 2019-nCoV Guanine-N7 methyltransferase is produced by our E.coli expression system and the target gene encoding Ala1-Gln527 is expressed with a 6His tag at the N-terminus.Background:The nonstructural protein (nsp) 14 of SARS-CoV 2 was identified as a cap (guanine-N7)-methyltransferase (N7-MTase). Nsp14 of coronaviruses two different activities: an exoribonuclease activity acting on both ssRNA and dsRNA in a 3" to 5" direction and a N7-guanine methyltransferase activity. It may be involved in the proof-reading ability during the viral RNA replication and transcription. GTP, dGTP as well as cap analogs GpppG, GpppA and m7GpppG could be methylated by nsp14.positive-stranded RNA genome of the coronaviruses is translated from ORF1 to yield polyproteins that are proteolytically processed into intermediate and mature nonstructural proteins (nsps). SARS-CoV 2 polyproteins incorporate 16 protein domains (nsps). The putative non-structural protein 2 (nsp2) of SARS-CoV plays an important role in viral transcription and replication, and is an attractive target for anti-SARS drug development.Formulation:Supplied as a 0.2 μm filtered solution of PBS, 10% Glycerol, pH 7.4.Purity:> 85 % as determined by reducing SDS-PAGE.Endotoxin:< 1.0 EU per µg as determined by the LAL method.Shipping:This product is provided as liquid. It is shipped at frozen temperature with blue ice/gel packs. Upon receipt, store it immediately at<-20°C. Avoid freeze-thaw cycles.
