3. Conclusion

The main enzyme families found in human beings were presented.

At this stage, the main enzymatic catalysts present in acellular and cellular prokaryotes and eukaryotes have been reviewed.

We now need to look at the deficiencies or overexpressions of certain human enzymes that can give rise to certain genetic pathologies, as well as the catalysts of pathogens that induce infections.

When enzymes mutate in living organisms, this can have harmful, even lethal consequences, as in the case of human genetic pathologies. It can also represent a life-saving opportunity for all species to evolve. In the case of certain pathogenic micro-organisms, these mutations can lead to the evasion of drug treatments. The result is a beneficial effect for the "aggressor" species, much less so for the "aggressed" species.
