G6PD deficiency results from mutations in the G6PD gene. G6PD gene contributes to the production of glucose-6-phosphate dehydrogenase. Chemical reactions involving glucose-6-phosphate dehydrogenase produce compounds that prevent reactive oxygen species from building up to toxic levels within red blood cells. If a reduction in the amount of ...
Glucose 6-phosphatase-β is a ubiquitously expressed, 346-amino acid membrane protein that shares 36% sequence identity with glucose 6-phosphatase-α. Within the glucose 6-phosphatase-β enzyme, sequence alignments predict that its active site contains His167, His114, and Arg79.
Glucose-6-phosphatase is an enzyme located on the inner membrane of the endoplasmic reticulum. The catalytic unit is associated with a calcium binding protein, and three transport proteins (T1, T2, T3) that facilitate movement of glucose-6-phosphate (G6P), phosphate, and glucose (respectively) into and out of the enzyme.
Glucose-6-phosphate dehydrogenase deficiency is very common worldwide, and causes acute hemolytic anemia in the presence of simple infection, ingestion of fava beans, or reaction with certain medicines, antibiotics, antipyretics, and antimalarials. [3] Cell growth and proliferation are affected by G6PD. [20]
Hypophosphatemia is an electrolyte disorder in which there is a low level of phosphate in the blood. [1] Symptoms may include weakness, trouble breathing, and loss of appetite. [1]
If glycogenolysis is taking place in the liver, G-6-P can be converted to glucose by the enzyme glucose 6-phosphatase (G6Pase); the glucose produced in the liver is then released to the bloodstream for use in other organs. Muscle cells in contrast do not have the enzyme glucose 6-phosphatase, so they cannot share their glycogen stores with the ...
The cleaved molecule is in the form of glucose 1-phosphate, which can be converted into G6P by phosphoglucomutase. Next, the phosphoryl group on G6P can be cleaved by glucose 6-phosphatase so that a free glucose can be formed. This free glucose can pass through membranes and can enter the bloodstream to travel to other places in the body.
This gene encodes the catalytic subunit of glucose 6-phosphatase (G6Pase). G6Pase is located in the endoplasmic reticulum (ER) and catalyzes the hydrolysis of glucose 6-phosphate to glucose and phosphate in the last step of the gluconeogenic and glycogenolytic pathways. [5]
