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. Webreduction of DHF to THF (5,6,7,8-tetrahydrofolate). The tight coupling between TS and DHFR or FolA is required in order to maintain the pool of reduced folates.
