  A search for supersymmetry is presented based on events with at least one
photon, jets, and large missing transverse momentum produced in proton-proton
collisions at a center-of-mass energy of 13 TeV. The data correspond to an
integrated luminosity of 35.9 fb$^{-1}$ and were recorded at the LHC with the
CMS detector in 2016. The analysis characterizes signal-like events by
categorizing the data into various signal regions based on the number of jets,
the number of b-tagged jets, and the missing transverse momentum. No
significant excess of events is observed with respect to the expectations from
standard model processes. Limits are placed on the gluino and top squark pair
production cross sections using several simplified models of supersymmetric
particle production with gauge-mediated supersymmetry breaking. Depending on
the model and the mass of the next-to-lightest supersymmetric particle, the
production of gluinos with masses as large as 2120 GeV and the production of
top squarks with masses as large as 1230 GeV are excluded at 95% confidence
level.
