Function
function
Catalyzes the ADP transfer from ATP to D-glycero-beta-D-manno-heptose 1-phosphate, yielding ADP-D-glycero-beta-D-manno-heptose.
Catalyzes the phosphorylation of D-glycero-D-manno-heptose 7-phosphate at the C-1 position to selectively form D-glycero-beta-D-manno-heptose-1,7-bisphosphate.
Catalytic activity
- ATP + D-glycero-beta-D-manno-heptose 1-phosphate + H+ = ADP-D-glycero-beta-D-manno-heptose + diphosphate
Pathway
Bacterial outer membrane biogenesis; LPS core biosynthesis.
Nucleotide-sugar biosynthesis; ADP-L-glycero-beta-D-manno-heptose biosynthesis; ADP-L-glycero-beta-D-manno-heptose from D-glycero-beta-D-manno-heptose 7-phosphate: step 1/4.
