By the term "enzyme" we mean specific organic compounds whose role is to accelerate chemical reactions in the body. All enzymes except ribozymes are proteins. All metabolic processes have their own specific enzymes, thanks to which the body can function normally. Out of thousands and thousands of enzymes in the human body, the absence of just one enzyme can represent a big problem for the whole health and the whole life. If a method for enzyme synthesis could be developed, a large number of the biggest and most complex health problems would be solved. Some of the most serious human diseases are caused by a lack of certain enzymes. Protein engineering and the world of science are trying to circumvent the problem of lack of natural enzymes by designing artificial enzymes. Artificially obtained enzymes represent the future in the world of science and medicine. Catalytic activity, specificity and complexity of the structure of natural enzymes are a great challenge in the synthesis of artificial enzymes. The goal is to design and synthesize an enzyme that will have the same or even better properties than natural enzymes. Space for growth and development, in the world of artificial enzymes, has also been found by nanotechnology with its nanoenzymes. Nanoenzymes could soon become part of everyday medicine and science. The future of artificial enzymes is bright and the room for development is very large. Future research has the task of improving already synthesized artificial enzymes, but also designing and synthesizing new ones.
