Latia neritoides is a small limpet-like snail that produces a bright green bioluminescence; it is found only in New Zealand streams. The light-emitting system is unique. Although Latia bioluminescence has been studied since 1880, its mechanism is unclear. Shimomura and Johnson clarified the elements of the mechanism, including the structures of luciferin and luciferase, in 1968. However, neither the emitter nor the mechanism of the excited state of luciferin has been determined. We studied molecular mechanisms to clarify the characteristics of luciferin and luciferase and to produce a new application for this system.

生物荧光的小型帽贝状蜗牛;它只出现在新西兰的溪流中。它的发光系统非常独特。虽然自 1880 年以来就有人对拉蒂亚
生物发光进行了研究,但其机理尚不清楚。1968 年,下村(Shimomura)和约翰逊(Johnson)阐明了该机制的要素,包括
荧光素和
荧光素酶的结构。然而,
荧光素激发态的发射体和机制均未确定。我们研究了分子机制,以阐明
荧光素和
荧光素酶的特性,并为这一系统开发出新的应用。
