QUÉ SIGNIFICA PEROXIDASE EN INGLÉS
Peroxidasa
Las peroxidasas son una gran familia de enzimas que típicamente catalizan una reacción de la forma: ROOR '+ donante de electrones + 2H + → ROH + R'OH Para muchas de estas enzimas el sustrato óptimo es peróxido de hidrógeno, pero otros son más activos con hidroperóxidos orgánicos tales como Como peróxidos lipídicos. Las peroxidasas pueden contener un cofactor hemo en sus sitios activos, o alternativamente restos de cisteína o selenocisteína redox activos. La naturaleza del donante de electrones es muy dependiente de la estructura de la enzima. ▪ Por ejemplo, la peroxidasa de rábano picante puede utilizar una variedad de compuestos orgánicos como donantes y aceptores de electrones. La peroxidasa de rábano picante tiene un sitio activo accesible, y muchos compuestos pueden llegar al sitio de la reacción. ▪ Debido a que existe un sitio activo muy cerrado, para una enzima como la citocromo c peroxidasa, los compuestos que donan electrones son muy específicos. Aunque los mecanismos exactos aún no se han dilucidado, las peroxidasas son conocidos por desempeñar un papel en el aumento de las defensas de una planta contra patógenos. Las peroxidasas se utilizan a veces como marcador histológico. La citocromo c peroxidasa se utiliza como un modelo soluble, fácilmente purificado para la citocromo c oxidasa.
definición de peroxidase en el diccionario inglés
La definición de peroxidasa en el diccionario es cualquiera de un grupo de enzimas que catalizan la oxidación de un compuesto por la descomposición del peróxido de hidrógeno o un peróxido orgánico. Por lo general, consisten en una proteína combinada con hemo.
