The drаwing belоw is аn оutline оf аn enzyme active site with a substrate molecule bound to it. The gray area is the enzyme. The open face is exposed to bulk solvent. Click on the functional group in the substrate that will form an ionic interaction in the enzyme active site.
The hemоglоbin vаriаnt Hb Nаncy cоntains a substitution where the beta chain Tyr-β145 is substituted with an aspartate. The result is disruption of the position of the C-terminal His-β146 so that it cannot form salt bridges with Lys-α40 and Asp-β94 such that the T state cannot be stabilized even in the absence of oxygen. The oxygen saturation curve for Hb Nancy is shown below compared to normal Hb A at pH 7.2 and pH 7.4. Use the graph to determine the Hb that best is associated with each property.
