Caffeoylpyruvate hydrolase; part of the gene cluster that mediates the fungal bioluminescence cycle. Involved in the recycling of oxyluciferin, a pyruvic acid adduct of caffeic acid, to caffeic acid. The fungal bioluminescence cycle begins with the hispidin synthetase that catalyzes the formation of hispidin which is further hydroxylated by the hispidin-3-hydroxylase, yielding the fungal luciferin 3-hydroxyhispidin. The luciferase then produces an endoperoxide as a high-energy intermediate with decomposition that yields oxyluciferin (also known as caffeoylpyruvate) and light emission. Oxyluciferin can be recycled to caffeic acid by caffeoylpyruvate hydrolase (Probable)
