El pirofosfato pudo haber sido la molécula acarreadora de energía precursora del ATP en la atmósfera primigenia. Durante la evolución, el ATP sustituyó al pirofosfato mostrando una mayor versatilidad funcional. Paralelamente, los sistemas encargados de su síntesis o hidrólisis, H+ pirofosfatasas, ATPasas y la ATP sintasa mitocondrial, fueron mostrando mayor complejidad estructural y diversificado funcionalmente utilizando parte de sus componentes estructurales para realizar funciones diferentes de la síntesis o hidrólisis del ATP. Estos hallazgos han revolucionado el campo de la bioenergética tradicional y abierto nuevos caminos a la investigación de procesos normales y patológicos.
Palabras Clave: ATP sintasa; estructura; función; localizaciones ectópicas
In the primitive atmosphere, pyrophosphate could have been the energy carrier molecule that gave rise to ATP. During evolution, ATP substituted pyrophosphate because it showed a higher functional versatility. At the same time, the systems that carried out its synthesis or hydrolysis, such as the H+ pyrophosphatases, ATPases and mitocondrial ATP synthases showed a higher structural complexity and also diversified functionally by using a part of their structural components in order to perform functions different from those of ATP synthesis or hydrolysis. such findings have revolutionized the field of traditional bioenergetics and opened new pathways to the research of pathological and normal processes.
Key Words: ATP synthase; structure; function; ectopic localization
