NACIMIENTO DE LA CINÉTICA ENZIMÁTICA de aquel encuentro en entre Leonor Michaelis y Maud Menten, y de su estrecha colaboración investigadora. 12 تموز (يوليو) 1, × ; KB. Michaelis Menten curve 1, × ; KB. Michaelis Menten. En bioquímica, el diagrama Hanes–Woolf se emplea como herramienta gráfica para calcular los parámetros cinéticos de una enzima. En él se representa la relación concentración de sustrato/velocidad de reacción frente a la concentración de sustrato [S]. Es una de las formas de linealizar la ecuación de Michaelis-Menten.

Inicialment, l’enzim transforma el substrat en producte seguint un comportament lineal.

A baixes concentracions ebzimatica substrat, l’enzim roman en un equilibri constant entre la forma lliure E i el complex enzim-substrat ES. Encara que aquests objectius encara no s’han arribat a assolir en eucariotess’han obtingut certs progressos en bacterisutilitzant models del metabolisme d’ Escherichia coli.

Per a un enzim que uneixi dos substrats Cinetida i B, i els transformi en dos productes P i Q, existeixen dos tipus de mecanismes descrits fins ara.

Entre els enzims amb aquest tipus de mecanisme es pot trobar alguna oxidoreductasacom la tioredoxima peroxidasa[16] transferasescomo l’ acil-neuraminat citidil transferasa[17] i serin proteasascomo la tripsina i la quimiotripsina.

El coeficient de Hill pot prendre valors majors o menors que Posteriorment, quan arriba a l’estat estacionari, la velocitat disminueix.
