Evolución filogenética y adaptación ambiental de la Rubisco
(2018-06-13)La Rubisco cataliza la conversión de carbono inorgánico a orgánico, sosteniendo la mayoría de las cadenas alimenticias y la vida en la Tierra. Presenta importantes ineficiencias catalíticas, como son una catálisis lenta, ... -
Evolutionary trends in RuBisCO kinetics and their co-evolution with CO2 concentrating mechanisms
(Wiley, 2020)RuBisCO-catalyzed CO2 fixation is the main source of organic carbon in the biosphere. This enzyme is present in all domains of life in different forms (III, II, and I) and its origin goes back to 3500 Mya, when the atmosphere ... -
