Resumen:
The invertase from Solanum tuberosum is inhibited by its reaction products, fructose and glucose. The inhibition by fructose fits well with a case of inhibition through two interacting sites (Ki 0.18 M, UK, 0.33 M). Thisinhibition is not suppressed by proteins as occurs with invertases inhibited in a simple way by their reaction products. Thus fructose could be an important effector, in uivo, of this enzyme. Glucose is a non-competitive classical inhibitor (Ki 1.02 M) whose inhibitory action is not suppressed by proteins.
