IUBMB Enzyme Nomenclature


Accepted name: phosphoramidate—hexose phosphotransferase

Reaction: phosphoramidate + D-hexose = NH3 + α-D-hexose 1-phosphate

Other name(s): phosphoramidate-hexose transphosphorylase; phosphoramidic-hexose transphosphorylase; phosphoramidate:hexose 1-phosphotransferase

Systematic name: phosphoramidate:D-hexose 1-phosphotransferase

Comments: Activity is observed with several hexoses; of these glucose is the best substrate and the product from it is α-D-glucose 1-phosphate. The phosphoramidate donor can be replaced by N-phosphoglycine and by an N-phosphohistidine. May be identical with EC glucose-6-phosphatase.
