Catalyzes the dephosphorylation of undecaprenyl diphosphate (UPP). Confers resistance to bacitracin. di-trans,octa-cis-undecaprenyl diphosphate + H2O = di-trans,octa-cis-undecaprenyl phosphate + H(+) + phosphate Bacitracin is thought to be involved in the inhibition of peptidoglycan synthesis by sequestering undecaprenyl diphosphate, thereby reducing the pool of lipid carrier available. Was identified as a high-confidence drug target. Belongs to the UppP family. Truncated N-terminus.
