Recombinant Proteins from Domestic Animals
Proteins are the direct product of genes. They play a major role in living organisms. Some of them are enzymes, others are hormones, blood factors etc. For many years the only source of proteins was living organisms themselves. Proteins have a too complex structure to be synthesized chemically at a reasonable cost. They must therefore be biosynthesized. The techniques of genetic engineering have offered the possibility to reprogram living organisms by transferring isolated genes coding for proteins. The proteins synthesized in this manner are named recombinant proteins. The preparation of recombinant proteins is currently one of the major successes ofbiotechnology. Human insulin, human growth hormone etc. synthesized by bacteria are now used as pharmaceuticals. An additional advantage of recombinant proteins is that various forms of the molecules can be prepared by mutating the corresponding genes.
