Abstract

Genetic engineering is often used in the field of drug discovery to produce many copies of a specific enzyme in an attempt to discover possible inhibitors of the enzyme. The specific proteins FabH and FabB in E. coli are enzymes that serve as catalysts for fatty acid biosynthesis, a process essential for cell survival. Inhibiting specific steps in the fatty acid biosynthesis pathway has proven to be an effective strategy for developing antibacterial agents. Expression of FabH and FabB from plasmids in a molecular cloning experiment may be used for experiments to find possible inhibitors and antibacterial targets against E. coli bacteria. Using Polymerase Chain Reactions (PCR), a specific section of the isolated DNA for both FabB and FabH enzymes in E. coli were exponentially replicated. Plasmids containing the gene inserts were confirmed with a selective marker and amplified by insertion into an E. coli bacterial cell using heat shock and LiAc. The cells were replicated, and therefore the plasmid amplified, so that each cell had the same plasmid with the DNA of interest. Expression of the enzymes of interest was evaluated using gel electrophoresis.
