Reaction: Unknown sepiapterin synthase transforms PTHP to sepiapterin

- in pathway: Tetrahydrobiopterin (BH4) synthesis, recycling, salvage and regulation
In an alternative salvage pathway for BH4 synthesis, dyspropterin (PTHP) may be transformed to sepiapterin, possibly non-enzymatically or by an unknown sepiapterin synthase enzyme (Crabtree & Channon 2011).
