Abstract excerpt
The D1 gene encoding the large subunit of vaccinia virus mRNA capping enzyme was expressed in Escherichia coli BL21(DE3) under the control of a bacteriophage T7 promoter. Guanylyltransferase activity (assayed as the formation of a covalent enzyme-guanylate complex) was detected in soluble lysates of these bacteria. Two major species of protein-GMP complex were formed, one of Mr 95,000 (corresponding in size to...
