Exploring Pathway Databases

Saccharomyces Genome Database

  • GDH2 has a homolog in humans. A deficiency of the human homologs, GLUD1 and GLUD2, has been known to cause hyperinsulinism-hyperammonemia syndrome and various neurological disorders.
  • Gene Expression Regulation:
    • GDH1: expression regulated by nitrogen and carbon sources
    • GDH3: expression regulated by nitrogen and carbon sources
    • GDH2: expression sensitive to nitrogen catabolite repression and intracellular ammonia levels
    • GLN1: expression regulated by nitrogen source and amino acid limitation
    • GLT1: expression regulated by nitrogen source
  • There are 56 pathways listed in the database that L-glutamate participates in
  • Pathway:

KEGG

  • KEG Pathway
  • The information provided in KEGG is similar to SGD but KEGG includes 3-D structures of the enzymes and AA and NT sequences.
