Comments [?]

Function 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.
Catalyzes the ADP transfer from ATP to D-glycero-beta-D-manno-heptose 1-phosphate, yielding ADP-D-glycero-beta-D-manno-heptose.
Catalytic activity RHEA:27473: ATP + D-glycero-beta-D-manno-heptose 7-phosphate = ADP + D-glycero-beta-D-manno-heptose 1,7-bisphosphate + H(+)
EC 2.7.1.167
RHEA:27465: ATP + D-glycero-beta-D-manno-heptose 1-phosphate + H(+) = ADP-D-glycero-beta-D-manno-heptose + diphosphate
EC 2.7.7.70
Pathway 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.
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 3/4.
Subunit Homodimer.
Similarity In the N-terminal section; belongs to the carbohydrate kinase PfkB family.
In the C-terminal section; belongs to the cytidylyltransferase family.
