isoenzima
Sign in to saveAlso known as isoenzymes, multiple forms of enzymes, izoenzymy, isoenzyme, isozymes
In biochemistry, isozymes (also known as isoenzymes or more generally as multiple forms of enzymes or isoforms) are enzymes that differ in amino acid sequence but catalyze the same chemical reaction. Isozymes usually have different kinetic parameters (e.g. different KM values), or are regulated differently. They permit the fine-tuning of metabolism to meet the particular needs of a given tissue or developmental stage.

Las isoenzimas o isozimas son enzimas que difieren en la secuencia de aminoácidos, pero que catalizan la misma reacción química. Estas enzimas suelen mostrar diferentes parámetros cinéticos (i.e. diferentes valores de KM), o propiedades de regulación diferentes. La existencia de las isoenzimas permite el ajuste del metabolismo para satisfacer las necesidades particulares de un determinado tejido o etapa del desarrollo. En bioquímica, las isoenzimas son isoformas (variantes estrechamente relacionadas) de las enzimas. En muchos casos, son codificadas por genes homólogos que han divergido con el tiempo. Aunque de forma estricta, las aloenzimas representan enzimas de diferentes alelos de un mismo gen y las isoenzimas representan enzimas de diferentes genes cuyos productos catalizan la misma reacción, los dos términos se suelen usar indistintamente.
