EC 2.7.1.167     
Accepted name: D-glycero-β-D-manno-heptose-7-phosphate kinase
Reaction: D-glycero-β-D-manno-heptose 7-phosphate + ATP = D-glycero-β-D-manno-heptose 1,7-bisphosphate + ADP
Other name(s): heptose 7-phosphate kinase; D-β-D-heptose 7-phosphotransferase; D-β-D-heptose-7-phosphate kinase; HldE1 heptokinase; glycero-manno-heptose 7-phosphate kinase; D-β-D-heptose 7-phosphate kinase/D-β-D-heptose 1-phosphate adenylyltransferase; hldE (gene name); rfaE (gene name)
Systematic name: ATP:D-glycero-β-D-manno-heptose 7-phosphate 1-phosphotransferase
Comments: The bifunctional protein hldE includes D-glycero-β-D-manno-heptose-7-phosphate kinase and D-glycero-β-D-manno-heptose 1-phosphate adenylyltransferase activity (cf. EC 2.7.7.70). The enzyme is involved in biosynthesis of ADP-L-glycero-β-D-manno-heptose, which is utilized for assembly of the lipopolysaccharide inner core in Gram-negative bacteria. The enzyme selectively produces D-glycero-β-D-manno-heptose 1,7-bisphosphate [5].
