Our second approach separates the genes, allowing us to see if the genes can be expressed more efficiently when they are under the control of one promoter each. The separation also permits us to induce one promoter and therefore express one gene at a time. With the genes expressed independently, we are able to control the production of each enzyme and ensure equal amounts are expressed. The glycolaldehyde reductase enzyme will be under the control of the pBAD promoter; the glycolaldehyde dehydrogenase enzyme will be under the control of the pLAC promoter. Because we are employing the lac promoter, we must have the lacI operon to act as the repressor. The diagrams below depict the cassette orientation within each plasmid. For each of these set-ups, we will use restriction enzymes, gel purifications, and then ligations to piece together each sub-construct. The process is lengthy in time because of the time involved for transformations, liquid cultures, and enzymatic digests. | Our second approach separates the genes, allowing us to see if the genes can be expressed more efficiently when they are under the control of one promoter each.

Our second approach separates the genes, allowing us to see if the genes can be expressed more efficiently when they are under the control of one promoter each. The separation also permits us to induce one promoter and therefore express one gene at a time. With the genes expressed independently, we are able to control the production of each enzyme and ensure equal amounts are expressed. The glycolaldehyde reductase enzyme will be under the control of the pBAD promoter; the glycolaldehyde dehydrogenase enzyme will be under the control of the pLAC promoter. Because we are employing the lac promoter, we must have the lacI operon to act as the repressor. The diagrams below depict the cassette orientation within each plasmid. For each of these set-ups, we will use restriction enzymes, gel purifications, and then ligations to piece together each sub-construct. The process is lengthy in time because of the time involved for transformations, liquid cultures, and enzymatic digests.
