Glutamate dehydrogenase of the unicellular green alga Scenedesmus acutus : Substrate-induced conformational transition.

V R Shatilov1, H Sund.   

Abstract

The coenzyme-non-specific glutamate dehydrogenase (EC 1.4.1.3) from Scenedesmus acutus in inhibited by p-hydroxymercuribenzoate only in the deamination reaction. From this result and from its stability in the presence of urea it is concluded that this enzyme exhibits and equilibrium between three conformations: aminating and deaminating conformations induced by NADH-2-oxoglutarate and NAD(+)-glutamate, respectively, and the "native" conformation in the absence of substrates.
