The biosynthesis of tetrahydrobiopterin (BH4) from dihydroneopterin triphosphate (NH2P3) was studied in human liver extract. The phosphate-eliminating enzyme (PEE) was purified approximately 750-fold. The conversion of NH2P3 to BH4 was catalyzed by this enzyme in the presence of partially purified sepiapterin reductase, Mg2+, and NADPH. The PEE is heat stable when heated at 80°C for 5 min. It has a molecular weight of 63 000 daltons. One possible intermediate 6-(1-hydroxy-2-oxopropyl)5,6,7,8-tetrahydropterin(2-oxo-tetrahydropte rin) was formed upon incubation of BH4 in the presence of sepiapterin reductase and NADP+ at pH 9.0. The reduction of this compound with NaBD4 yielded monodeutero-, threo-, and erythro-BH4; the deuterium was incorporated at the 2 position. This and the UV spectra were consistent with a 2-oxo-tetrahydropterin structure. Dihydrofolate reductase (DHFR) catalyzed the reduction of BH2 into BH4 and was found to be specific for the pro-R-NADPH side. The sepiapterin reductase catalyzed the transfer of the pro-S hydrogen of NADPH during the reduction of sepiapterin into BH2. In the presence of crude liver extracts, the conversion of NH2P3 into BH4 requires NADPH. Two deuterium atoms were incorporated from (4S-2H)NADHP in the 1 and 2 position of the BH4 side chain. The incorporation of one hydrogen from the solvent was found at position C(6). These results are consistent with the occurrence of an intramolecular redox exchange between the pteridine nucleus and the side chain and formation of 6-pyruvoyl-5,6,7,8-tetrahydropterin(tetrahydro-1-2-dioxopterin) as an intermediate (PMID: 3930838).
