General annotation (Comments)

Function

Catalyzes the isomerization of sedoheptulose 7-phosphate in D-glycero-D-manno-heptose 7-phosphate By similarity. HAMAP-Rule MF_00067

Catalytic activity

D-sedoheptulose 7-phosphate = D-glycero-D-manno-heptose 7-phosphate. HAMAP-Rule MF_00067

Cofactor

Binds 1 zinc ion per subunit By similarity. HAMAP-Rule MF_00067

Pathway

Carbohydrate biosynthesis; D-glycero-D-manno-heptose 7-phosphate biosynthesis; D-glycero-alpha-D-manno-heptose 7-phosphate and D-glycero-beta-D-manno-heptose 7-phosphate from sedoheptulose 7-phosphate: step 1/1. HAMAP-Rule MF_00067

Subunit structure

Homotetramer By similarity. HAMAP-Rule MF_00067

Subcellular location

Cytoplasm By similarity HAMAP-Rule MF_00067.

Miscellaneous

The reaction produces a racemic mixture of D-glycero-alpha-D-manno-heptose 7-phosphate and D-glycero-beta-D-manno-heptose 7-phosphate By similarity.

B.aphidicola is not able to make lipopolysaccharides (LPS), and except lpcA and kdtB, the genes responsible for the biosynthesis of the LPS components are missing from the genome.

Sequence similarities

Belongs to the SIS family. GmhA subfamily.

Contains 1 SIS domain.
