In this paper, we discuss the predicted proton lifetimes in minimal supersymmetric (SUSY) SU(5) grand unified theory (GUT) with gauge mediated supersymmetry breaking (GMSB). We focus on the case of 5 + \mathbf5 messengers and determine the low-scale mass spectrum of the scalar particles and gauginos using the renormalization group equations. With the obtained mass spectrum, we calculate the dominant proton decay mode for SUSY SU(5) GUT, p → K+ ν. In our setup, we assume the messenger scale to be O(103) TeV in order to obtain a proper Higgs mass in GMSB scenario. For this messenger scale, we find the proton lifetime is consistent with current experimental limits and can be tested by future proton decay experiments.
