Abstract excerpt
It has been identified that a TEV protease (TEVp) variant, TEVp(5M), displays improved solubility. Here, we constructed fifteen TEVp(5M) variants with one or more of six rare arginine codons in the coding sequence replaced with abundant E. coli arginine codons. These codon variants expressed in either E. coli BL21 (DE3) or Rossetta (DE3) showed different solubility and activity. Supply of rare tRNAs increased the...
