This entry represents the C-terminal domain of phosphoglucomutase-1 (PGM1) from human, and its homologues from vertebrates and fungi, which catalyses the bi-directional interconversion between alpha-D-glucose 1-phosphate (G1P) and alpha-D-glucose 6-phosphate (G6P), a reaction that is essential for normal carbohydrate metabolism and is also important in the cytoplasmic biosynthesis of nucleotide sugars needed for glycan biosynthesis [2-5]. This domain contains a six-stranded antiparallel beta-sheet with two alpha-helices lying on the face of the sheet opposite the active site which is located centrally, in a deep cleft between the four domains of these proteins [1-5]. This domain contains the phosphate-binding loop which interacts with the substrate phosphate moiety [5].
