Reaction: Sepiapterin reductase (SPR) is phosphorylated by Ca2+/calmodulin-dependent protein kinase II

- in pathway: Tetrahydrobiopterin (BH4) synthesis, recycling, salvage and regulation
To become active, sepiapterin reductase (SPR) must first be phosphorylated (serine 213 in humans) by Ca2+/calmodulin-dependent protein kinase II (Fujimoto et al. 2002, Katoh et al. 1994).
