The enzyme imidazoleglycerol-phosphate dehydratase (EC 4.2.1.19) catalyzes the chemical reactionD-erythro-1-(imidazol-4-yl)glycerol 3-phosphate 3-(imidazol-4-yl)-2-oxopropyl phosphate + H2O
Inhibition
Certain compounds that inhibit IGPD have been used as herbicides as animals do not have this protein. One of these inhibitors is 3-Amino-1,2,4-triazole (3-AT), which has also been used as a competitive inhibitor of the product of the yeastHIS3 gene (another IGPD), e.g. in the yeast two-hybrid system. ==Structural studies==
