QUÉ SIGNIFICA UREASE EN INGLÉS

Ureasa

Urease

Las ureasas, funcionalmente, pertenecen a la superfamilia de amidohidrolasas y fosfotriestreasas. Es una enzima que cataliza la hidrólisis de la urea en dióxido de carbono y amoníaco. La reacción se produce de la siguiente manera: 2CO + H2O → CO2 + 2NH3 Más específicamente, la ureasa cataliza la hidrólisis de urea para producir amoníaco y carbamato; El carbamato producido se degrada posteriormente por hidrólisis espontánea para producir otro amoníaco y ácido carbónico. La actividad de la ureasa tiende a aumentar el pH de su ambiente, ya que produce amoníaco, una molécula básica. Las ureas se encuentran en numerosas bacterias, hongos, algas, plantas y algunos invertebrados, así como en los suelos, como una enzima del suelo. Son metaloenzimas que contienen níquel de alto peso molecular. En 1926, James B. Sumner, profesor asistente en la Universidad de Cornell, demostró que la ureasa es una proteína examinando su forma cristalizada. El trabajo de Sumner fue la primera demostración de que una proteína pura puede funcionar como una enzima, y ​​finalmente llevó al reconocimiento de que la mayoría de las enzimas son de hecho proteínas y el premio Nobel de química a Sumner en 1946. La estructura de la ureasa fue la primera Resuelto por PA Karplus en 1995.

Ureases, functionally, belong to the superfamily of amidohydrolases and phosphotriestreases. It is an enzyme that catalyzes the hydrolysis of urea into carbon dioxide and ammonia. The reaction occurs as follows: 2CO + H2O → CO2 + 2NH3 More specifically, urease catalyzes the hydrolysis of urea to produce ammonia and carbamate; the carbamate produced is subsequently degraded by spontaneous hydrolysis to produce another ammonia and carbonic acid. Urease activity tends to increase the pH of its environment as it produces ammonia, a basic molecule. Ureases are found in numerous bacteria, fungi, algae, plants and some invertebrates, as well as in soils, as a soil enzyme. They are nickel-containing metalloenzymes of high molecular weight. In 1926, James B. Sumner, an assistant professor at Cornell University, showed that urease is a protein by examining its crystallized form. Sumner's work was the first demonstration that a pure protein can function as an enzyme, and led eventually to the recognition that most enzymes are in fact proteins, and the award of the Nobel prize in chemistry to Sumner in 1946. The structure of urease was first solved by P. A. Karplus in 1995.
