Query: Low Energy Consequences of Five Dimensional SO(10)   We consider five dimensional (5D) supersymmetric SO(10) compactified on the
orbifold $S^1/(Z_2\times Z_2')$ such that the SO(10) gauge symmetry is broken
on both fixed points (branes), and the residual gauge symmetry is
$SU(3)_c\times SU(2)_L\times U(1)_Y\times U(1)_X$. We explore one example in
which the gauge symmetries on the two branes are respectively $SU(5)\times
U(1)_X$ and $SU(4)_c\times SU(2)_L\times SU(2)_R$, and the MSSM gauge symmetry
is recovered by the usual Higgs mechanism. We discuss how fermion masses and
mixings can be understood in this framework by introducing a flavor $U(1)_F$
symmetry. Unification of the MSSM gauge couplings and proton stability are also
considered. An order of magnitude increase in sensitivity could reveal proton
decay.
