Researchers have confirmed the enzyme caffeylpyruvate hydrolase (CPH) completes the recycling loop in the fungal bioluminescence pathway, sustaining continuous light emission in fungi. The enzyme breaks down oxyluciferin into caffeic and pyruvic acids, allowing the fungus to recycle light-producing molecules while potentially recovering some of the energy used in the process. The findings, published in The FEBS Journal, could enable the design of brighter, more efficient self
