The tight coupling between TS and DHFR or FolA is required in order to maintain the pool of reduced folates. THF is required in a number of one-carbon reactions in DNA, RNA, and protein synthesis (2). These two enzymes have been the targets of numerous chemotherapeutic inhibitors, ...
WebFeb 28, 2024 · The enzyme DHFR (dihydrofolate reductase) then restores the THF pools by reducing DHF to THF. In cancer cells, the 1C pathway can be viewed as a THF cycle that uses 1C units from serine to... WebWe show that DHFR utilises 10-CHO-DHF about one third as efficiently as it utilises DHF. The 10-CHO-DHF is also utilised (as a formyl group donor) by PurH albeit slightly less efficiently than 10-CHO-THF. The utilisation of 10-CHO-DHF by DHFR is ~50 fold more efficient than its utilisation by PurH.
