WebTHF and DHF are unsubstituted folate species which do not play a direct metabolic role, but rather receive one-carbon moieties and transfer them toward either methylation-dependent or DNA-synthesis-dependent pathways (Fig. 4.3, pool 4). DHF reductase is a critical enzyme that is responsible for reducing folic acid and DHF into the metabolically ... WebNotably, when the ∆pabA strain harboured a folate transporter, it grew in the presence of 10-CHO-DHF alone, suggesting that it (10-CHO-DHF) can enter one-carbon metabolic pathway to provide the required metabolites. Thus, our studies reveal that both DHFR and PurH could utilise 10-CHO-DHF for folate homeostasis in E. coli. WebDownload scientific diagram Folate derivatives metabolism.

WebSep 8, 2009 · However, since the synthesis of folic acid (FA, pteroylglutamic acid) as a provitamin in 1945, DHFR has taken on another role: reduction of FA to 7,8-DHF . Folic … cyclopinclopanDihydrofolic acid (conjugate base dihydrofolate) (DHF) is a folic acid (vitamin B9) derivative which is converted to tetrahydrofolic acid by dihydrofolate reductase. Since tetrahydrofolate is needed to make both purines and pyrimidines, which are building blocks of DNA and RNA, dihydrofolate reductase is targeted by various drugs to prevent nucleic acid synthesis. cycloplegic eye refraction
