Introduction Protein Expression in Bacteria
Bacterial expression system is an ideal protein expression system of all time because of its nature. It often acts as the first choice in producing recombinant proteins and antibodies. Many bacteria have already been well characterized and investigated until now.
Among the huge number of bacteria, E. coli and B. subtilis cell lines are the most commonly used hosts for recombinant protein expression. They replicate extremely fast under the right condition at a low cost, while the expression level is high, which makes it an efficient and economical way for large scale production. Their genomes have been entirely sequenced and the genetic backgrounds and metabolic pathways are well known. Additionally, because of the simple structures, bacteria are more easily transfected than eukaryotes. These desirable characteristics make the expression procedure easier and quicker.
But every coin has two sides. Proteins with few modifications could be expressed in bacteria easily. While there is no nucleus, Golgi apparatus, and endoplasmic reticulum in bacteria. These structures are necessary in the process of cellular transport and post-translational modifications (PTMs). This leads to the incapability to produce membrane-bound proteins with bacterial expression systems, including glycophorins, several kinds of enzymes, and so on. Since such modifications are required in the correct folding, proteins produced in bacteria are often inactive and not functional. In terms of these respects, the eukaryotic expression system is more suitable to express these proteins that need folding, modification, and special structures, even if it is more expensive and takes more time than the bacterial expression system. Each expression system has its merits and demerits.
