additional information
additional information
-
non-standard kinetics at high glutamate and ATP concentrations, being partially inhibited by increasing concentrations of its principal substrate, dihydropteroate. Binding of dihydropteroate to the catalytic and inhibitory sites exhibits dissociation constants of 0.50 microM and 1.25 microM, respectively. Under lower co-substrate concentrations, data fit the Michaelis-Menten equation
