WebQuestion: Below is an extract which describes the mechanism of action of phosphohexose isomerase during the conversion of glucose 6-phosphate to fructose 6-phosphate. Fill in the missing words to complete the extract. Listed here is the pool of words to select from: break, carbonyl, cis-enediol, double, glutamate, histidine, hydroxyl, open, reformation, ring. WebTriose phosphate isomerase (TPI) deficiency is encoded by a gene on chromosome 12. Only one isozyme of TPI is produced and, thus, enzyme deficiency is shared by several tissues. At least 30 cases of TPI deficiency with hemolytic anemia have been described. Several different point mutations in the TPI gene have been identified (68,69).
The mechanism that GPI uses to interconvert glucose 6-phosphate and fructose 6-phosphate (aldose to ketose) consists of three major steps: opening the glucose ring, isomerizing glucose into fructose through an enediol intermediate, and closing the fructose ring.
