We point out a model independent upper bound on the total proton decay lifetime in the context of grand unified theories with the standard model matter content. We present a minimal realistic non-supersymmetric grand unified theory. It is shown that from the constraints coming from the unification of gauge interactions and the upper bound on the proton lifetime the model predicts light scalar leptoquarks. We conclude that this GUT model can be tested at the next generation of proton decay experiments and future colliders through the production of scalar leptoquarks.
