Enzymes are one of our main research and application for human health. It is generally globular proteins, acting alone or in larger complexes which serve a wide variety of biological functions inside living organisms. They are indispensable for signal transduction and cell regulation. Almost all metabolic processes in the cell need enzymes in order to occur at rates fast enough to sustain life. The set of enzymes made in a cell determines which metabolic pathways occur in that cell. Enzymes also determine cell metabolism to generate energy from cell and movement through generating muscle contraction. Other important biological function of enzymes is in the digestion to help absorbing nutrients.
The production of enzymes is a pursuit central to the modern biotechnology industry. The advent of genetic engineering has now facilitated the large-scale production of enzymes. This development is particularly significant with regard to the production of enzymes of therapeutic significance, which are now available in clinically useful quantities. The intestinal production and utilization of enzymes will continue to be of central importance in the biotechnology industry.
