pGTM_COV2_NSP5_004_SUMO
(Plasmid #190062)

• Purpose: Expresses SARS-CoV-2 3CLpro for the expression of the active mature protease
• Depositing Lab: Gaetano Montelione
• Publication: Mazzei et al STAR Protoc. 2023 May 5;4(2):102326. doi: 10.1016/j.xpro.2023.102326.

Backbone

• Vector backbone: pET15Sumo2_NESG
• Backbone manufacturer: Novagen/Northeast Structural Genomics Consortium
• Backbone size w/o insert (bp): 5737
• Total vector size (bp): 6604
• Modifications to backbone: An N-terminal 6X-His tag fused to the Smt3 gene (Sumo) of Saccharomyces cerevisiae as a purification/solubility enhancement cassette. BsaI sites are included in the cloning polylinker for scarless cloning of the SARS-CoV2 3CLpro and the production of a native, mature protein after cleavage from the Sumo fusion by Sumo protease (Ulp1).
