Abstract: Moonlighting proteins have the characteristic of being able to perform several biochemical functions with the same amino acid chain. These functions do not necessarily have to be related and normally one of them belongs to metabolism. The NOGD phenomenon occurs when an enzyme disappears from a metabolic pathway and its function is carried out by a completely different protein. Therefore, the aim of this study was to try to obtain evidence of a possible relationship and evolution between moonlighting proteins, which are little studied, and the NOGD phenomenon. To this end, phylogenetic trees of different enzymes extracted from protein databases that fit into both groups were created using bioinformatics tools. We have found that only one NOGD protein shares evolutionary lineage with the multifunctional protein. Therefore, it could be argued that the multifunctionality of the proteins has arisen from the NOGD phenomenon in different ways, such as gene duplication or through mutations that produce areas that are favourable for another function to be stored. After all, multifunctionality has evolutionary advantages such as greater versatility in DNA or protection of the individual from possible mutations that invalidate an enzyme. Be that as it may, the field of multifunctional proteins is developing in a way that will soon revolutionise the current biochemical perception of protein functionality.
