CC   -!- FUNCTION: Catalyzes the phosphorylation of D-glycero-D-manno-heptose 7-
CC       phosphate at the C-1 position to selectively form D-glycero-beta-D-
CC       manno-heptose-1,7-bisphosphate. {ECO:0000255|HAMAP-Rule:MF_01603}.
CC   -!- FUNCTION: Catalyzes the ADP transfer from ATP to D-glycero-beta-D-
CC       manno-heptose 1-phosphate, yielding ADP-D-glycero-beta-D-manno-heptose.
CC       {ECO:0000255|HAMAP-Rule:MF_01603}.
CC   -!- CATALYTIC ACTIVITY:
