Research Abstract |
Triggering mechanism of photoproteins has been investigated. The photoproteins have chromophore which is constituted from dehydrocoelenterazine (DCL). It demonstrated that oxo-complex of Fe ion made the luminescence speed fast, on the other hand, peroxide of hypochlorite made the luminescence speed slow. This specific reaction rate was proved to be useful for the identification of reactive oxygen species by using photoproteins. A convenient synthetic method was also established to prepare many kinds of DCLs.
