In the matter sector the UV divergences form several invariant structures some of which are cancelled in physical amplitudes. Thus, the theory which is in general non-renormalizable may be consistent and even finite. Consequences for the SUSY GUT models in the bulk are briefly discussed.Latex, 10 pages, 2 eps figures, V3: Eqs correctedHigh Energy Physics - Phenomenologytext
