Which of these genes has a homolog (similar gene related by descent) in humans? What disease does a deficiency of this gene cause in humans?
- GDH2; the homologs are GLUD1 and GLUD2. "Deficiencies in the human homologs of glutamate dehydrogenase, GLUD1 and GLUD2, have been linked to hyperinsulinism-hyperammonemia syndrome and various neurological disorders." GDH2
How is the expression of each of these genes regulated?
- GDH1- Expression is "regulated by nitrogen and carbon sources" GDH1
- GDH3- Expression is "regulated by nitrogen and carbon sources" GDH3
- GDH2- Expression is "sensitive to nitrogen catabolite repression and intracellular ammonia levels" GDH2
- GLN1- Expression is "regulated by nitrogen source and by amino acid limitation" GLN1
- GLT1- Expression is "regulated by nitrogen source" GLT1
"L-glutamate". How many pathways does it participate in?
- It is in reactions as a reactant 26 times. It is in reactions as a product 29 times. L-glutamate
