Salmonella paratyphi B (strain ATCC BAA-1250 / SPB7)
Bifunctional protein HldE
Including the following 2 domains:
D-beta-D-heptose 7-phosphate kinase
D-beta-D-heptose 1-phosphate adenosyltrans
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
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.
Carbohydrate kinase PfkB family; Cytidylyltransferase family
