Cofactor

Binds 1 manganese ion per subunit By similarity. HAMAP-Rule MF_00452

Pathway

Carbohydrate biosynthesis; gluconeogenesis. HAMAP-Rule MF_00452

Subunit structure

Monomer By similarity. HAMAP-Rule MF_00452

Subcellular location

Cytoplasm By similarity HAMAP-Rule MF_00452.

Sequence similarities

Belongs to the phosphoenolpyruvate carboxykinase [GTP] family.
