Dimetilsulfóxido reductasa (DMSOR)

Authors: Luna-Méndez, Miriam Yessenia;

Dimetilsulfóxido reductasa (DMSOR)

Abstract

Resumen Las enzimas son moléculas orgánicas importantes que ayudan a que sucedan determinadas reacciones químicas de forma más rápida en los seres vivos, siendo catalizadores en las reacciones de las células y el organismo. La DMSOR es parte de una familia de enzimas que contiene un ión de Molibdeno en su sitio activo que se encarga de reducir el dimetilsulfóxido (DMSO) a dimetilsulfuro (DMS), el DMSO es el aceptor de electrones terminal. En la reacción el oxígeno del DMSO se mueve hacia el molibdeno y luego se reduce a agua [1]. El molibdeno es un oligoelemento de la tabla periódica que también se encuentra presente en gran cantidad en el mar y en sistemas biológicos, además es importante por sus propiedades oxido-reductoras [2]. La enzima DMSO reductasa la podemos encontrar solo en las bacterias y arqueas, su función es degradar los oxoaniones y cataliza la transferencia de dos electrones y un oxígeno, para obtener como producto agua y DMS [3]. La enzima DMSOR es interesante y muy especial por su participación en diferentes ciclos naturales, como el del carbono, azufre y nitrógeno. La función de la enzima DMSO en el caso particular del ciclo del azufre, se oxida a metanosulfonatos, que condensan las nubes sobre los océanos y estas nubes nos ayudan a aumentar el albedo de la tierra y regular la temperatura, el albedo se produce con los rayos incidentes en la tierra y que luego se devuelven al espacio, el albedo de la tierra es 0.3 y en el mar es mucho más bajo, por esta razón la reacción que cataliza esta enzima podría ser de gran ayuda en el control climático [4, 5].
