WebOnce the folates pass through the FOLR genes (folate receptor genes), folates get converted to Dihydrofolate (DHF) via the DHFR genes (in Red) above. In addition, the gene DHFR, which is part of the folate family of genes (MTHFR), is directly connected to the folate receptor, that feeds the biopterin cycle in your brain. WebTwo folate synthesis mutants, with respective dihydrofolate synthase (DHFS) and dihydropteroate synthase (DHPS) deletions and requiring DHF for growth were exposed to sulfa drugs. The DHFS knockout mutant was inhibited, but the DHPS knockout mutant that was incapable of forming sulfa-DHP was insensitive.
