QUÉ SIGNIFICA ALLOZYME EN INGLÉS
Aloenzima
Las aloenzimas son formas variantes de una enzima que están codificadas por alelos diferentes en el mismo locus. Éstas se oponen a las isoenzimas, que son enzimas que realizan la misma función, pero que están codificadas por genes localizados en diferentes loci. Las aloenzimas son enzimas biológicas comunes que exhiben altos niveles de conservación evolutiva funcional a lo largo de phyla y reinos específicos. Son utilizados por los filogenéticos como marcadores moleculares para medir las historias evolutivas y las relaciones entre las diferentes especies de organismos. Esto se puede hacer porque las aloenzimas no tienen la misma estructura. Se pueden separar con electroforesis capilar Estas enzimas generalmente realizan funciones muy básicas que se encuentran comúnmente en todas las formas de vida, como la ADN polimerasa, la enzima que repara y copia el ADN. Los cambios significativos en esta enzima reflejan eventos significativos en la historia evolutiva de los organismos. Como se esperaba, la ADN polimerasa muestra diferencias relativamente pequeñas en su secuencia de aminoácidos entre filos e incluso reinos.
definición de allozyme en el diccionario inglés
