Abstract

Tailor-made proteins are playing a pivotal role in a plethora of different applications such as in biomedicine, in the chemical as well as food industry or in cosmetics. In a commonly used definition, the discipline ‘Protein Engineering’ describes the (more or less) targeted modification of already existing proteins, for instance, to enhance their biophysical or biochemical properties, whereas ‘Protein Design’ aims at generating artificial proteins displaying novel forms and functionalities. Presently engineered proteins affect the daily life of most of us – in fact with many of us often not even being aware of it. For example, engineered enzymes are exploited in order to process food or as ingredients in laundry detergents. A more obvious field in which protein engineering has made a tremendous impact is medicine. Many diagnostic reagents as well as the vast majority of biological therapeutics are engineered in one way or the other. A very prominent example of biomedical modalities are therapeutic antibodies. As of now, more than 100 antibodies have been approved by healthcare authorities. The vast majority – if not all – are artificially optimized molecules, for instance by humanization, by removal of sequence liabilities or by changes that improve the affinity for a cognate antigen. Furthermore, immunoglobulin-based derivatives that were engineered in a more sophisticated way are entering the clinical pipeline and the global market. Bispecific antibodies, for instance, bind two different antigens simultaneously thereby enabling to address the multifaceted nature of many diseases more adequately. Other approaches, such as antibody drug conjugates or prodrugs, aim at specifically activating the toxic properties of the therapeutic directly at the site of disease e.g. at the tumor tissue or the malignant cell to improve patient safety.
