AB We examine proton decay mediated by color-triplet Higgsinos in minimalsupersymmetric SU(5) grand unified theory in light of the discovery of the Higgs boson andthe absence of SUSY signals at the LHC. We pay special attention to various thresholdeffects arising from Planck-suppressed operators that affect the color-triplet Higgsino massand also allow for correcting the wrong mass relations for the light fermions. Our analysisallows for a non-universal SUSY spectrum with the third family sfermions having a separatemass compared to the first two families. We identify the allowed parameter space of themodel and show that the SUSY scalar masses are constrained by current limits from protonlifetime to be above 5TeV, while the glunio, Wino and the Higgsinos may be within reachof the LHC. When the SUSY scalar masses are required to be   30TeV, so that they arewithin reach of next generation collider experiments, we find that proton lifetime for thedecay p !  K+ is bounded by   (p !  K+)   1.1 × 1035 yrs
