Primary catalytic systems of biogenesis and structure-functional evolution of biocatalysers.

An important aspect of biological evolution is the development of biocatalyzers. The connection between abiotic and biological catalyzers is discussed, and the role of metal ions as primary catalysts is considered. The evolutionary demand for greater specificity and efficiency may have been fulfilled through the formation of metal-organic complexes and later through enzyme systems. Metal ions are probably responsible for the formation of some of the isoenzymes found in contemporary organisms.
