How did life and the first biological molecules emerge from the ancient prebiotic soup? A new study of original proteins goes a step further in understanding our origin.
The path to go Can replicate itself as one of the great mysteries of biology. The foundations of this process may depend on it And this . However, the fact that life cannot exist without the essential, central element seems to be the ability to manage energy. This is one of the definitions of life: the ability to store and use energy, whatever it may be.
Oxidation-reduction reactions based on life on Earth
However, the basic biological reactions that take place within cells are antioxidant-reduction reactions, which involve the exchange of electrons, thereby providing the required energy. This observation suggests that oxidation-reduction reactions should have been one of the first functions to be obtained by all. . Understanding the molecular evolution responsible for the catalysis of oxidation-reduction reactions will help unravel the mystery of the origin of life.
The researchers therefore discovered the evolution of these specific proteins with metallic components. It appears that these proteins are formed Will be seen again and again. Furthermore, the arrangements of these basic forms show that all of these proteins came from a single or very small number of ancestors.
Prefabricated blocks before assembly of the first proteins
Results of the study, published , Therefore suggests that the peptides that make up the original proteins should be used to facilitate the transfer of electrons, this action is absolutely essential for organisms. The basic elements for the required energy function, so they are widely reused and modified into different types of biological functions, which explains why we see the same structure in all the functions of organisms today.
