Other name(s): C55-isoprenyl diphosphatase; C55-isoprenyl pyrophosphatase; isoprenyl pyrophosphatase (ambiguous); undecaprenyl pyrophosphate phosphatase; undecaprenyl pyrophosphate pyrophosphatase; UPP phosphatase; Und-PP pyrophosphatase; UppP (ambiguous); BacA; undecaprenyl-diphosphate phosphohydrolase; undecaprenyl-diphosphatase

Systematic name: ditrans,octacis-undecaprenyl-diphosphate phosphohydrolase

Comments: Isolated from the bacteria Micrococcus lysodeikticus [1], Escherichia coli [2,3,5,6] and Bacillus subtilis [4]. The product of the reaction, ditrans,octacis-undecaprenyl phosphate, is essential for cell wall polysaccharide biosynthesis in these strains.
