What would happen to a mutated ATP synthase enzyme where the proton binding aspartate residue on the c subunits was mutated to an alanine
When the ATP synthase enzyme was mutated at the proton binding aspartate residue on the c subunits to alanine, the enzyme would not make ATP in the presence of a proton gradient.
What do you mean by ATP synthase?ATP synthase may be defined as the enzyme which catalyzes the synthesis of ATP from ADP and phosphate.
When the region of the enzyme ATP synthase was mutated, it changes the outcome. It affects the normal function and properties of the enzyme when there was a mutation.
Therefore, when the ATP synthase enzyme was mutated at the proton binding aspartate residue on the c subunits to alanine, the enzyme would not make ATP in the presence of a proton gradient.
