title: Chromophores in photoproteins of a glowing squid and mollusk.
abstract: Bioluminescence is a chemical reaction process for light emission in vivo. An organic substance is normally oxidized in the protein to obtain the energy required for the light emission. Determination of the structure of the substance is one of the most important parts of bioluminescent research. Photoproteins of a flying squid and a mollusk contain chromophores that are formed by connecting an apo-protein and dehydrocoelenterazine. The chromophore has a chemical structure that can emit light in a photoprotein. The structural analysis of the chromophores in the photoproteins is described.
