Nomenclature
This enzyme belongs to the family of hydrolases, to be specific, those acting on phosphoric monoester bonds. The systematic name is L-histidinol-phosphate phosphohydrolase. Other names in common use include histidinol phosphate phosphatase, L-histidinol phosphate phosphatase, histidinolphosphate phosphatase, HPpase, and histidinolphosphatase.
E. coli
In E. coli the enzyme encoded by the gene hisB is a fused imidazoleglycerol-phosphate dehydratase and histidinol-phosphatase.[1]
