A scientist wishes to produce a mammalian protein in E. coli. The protein is a glycoprotein with a molecular weight of 40,000. Approximately 20% of its mass is polysaccharide. The isolated protein is usually phosphorylated and contains three disulfide bonds. The cloned gene contains no introns A) What sequences or sites will be required in the vector to get this gene regulated, transcribed, and translated in E. coli? B) List two problems in E. coli that might arise in producing a protein identical to that isolated from mammalian cells and describe each problem in no more than two sentences.

How many ribosomes are actively synthesizing proteins at any instant in an E. coli cell growing with a doubling time of 45 minutes? Use the following assumptions in your calculations: a. The birth size of E. coli is 1 micron in diameter and 2 microns in length. b. The water content of the cell is 80%, and 50% of the dry cell mass is protein/enzymes. Also, the density of cell material is approximately 1 gram per mL. c. The rate of amino acid addition per ribosome is 20 amino acids per second, and the average molecular weight of a free amino acid is 126.

You would like to produce large amounts of a protein encoded by the gene wmu1 in E. coli using a specific plasmid. a). Draw an example of a plasmid that may be used in the expression of this gene with all required elements for expression in E. coli. b). What element(s) on the plasmid should you optimize in order to improve transcription of gene wmu1? c). What element(s) on the plasmid should you optimize in order to increase the replication of the plasmid in E. coli?
