Peptides are the ABCs of life.

The existence of all living organisms is possibly due to the interaction of peptides and de-oxyribonucleic acid - the main functional molecules in nature which carry all the hereditary information and determine all the functions of human body cells. Peptides regulate the expression of genes in all species of living organisms on Earth: bacteria, plants, insects, amphibians, birds, rodents and humans. The docking method made it possible to discover that short peptides consisting of 2-3-4 amino acids are able to create bonds with all spatial structures of the DNA double helix at all possible sites. Their effect leads to heterochromatin activation in the cell nuclei, to an increase in telomerase activity and in telomere length in fibroblasts, to the induction of differentiation of polypotent cells and to a decrease in the number of chromosomal aberrations. The results of molecular, genetic, clinical, experimental studies give irrefutable credence to a high activity of short peptides, to their ability to influence genetic expression, to improve synthesis of proteins in all living organisms. Peptides contribute to the functioning of organisms up to the highest species rank. Peptides are the main information molecules.
