The crystal structure of human phosphoglucose isomerase complexed with 5-phosphoarabinonate
Contents |
Overview
Phosphoglucose isomerase (PGI) is a workhorse enzyme of carbohydrate, metabolism that interconverts glucose 6-phosphate and fructose, 6-phosphate. Outside the cell, however, the protein appears to function as, a cytokine. A crystal structure of human PGI bound with, 5-phosphoarabinonate, a strong inhibitor that mimics the cis-enediol(ate), intermediate of the reaction, has been determined at 2.5 A resolution. The, structure helps to confirm the assignment of Glu357 as the base catalyst, in the isomerase reaction.
Disease
Known diseases associated with this structure: Hemolytic anemia due to glucosephosphate isomerase deficiency OMIM:[172400], Hydrops fetalis, one form OMIM:[172400]
