This communication reports the use of click chemistry to site-specifically conjugate bioluminescent Renilla luciferase proteins to gold nanoparticles (Au NPs) for sensing protease activity. The bioluminescent emission from luciferase was efficiently quenched by Au NPs, but significantly recovered after the proteolytic cleavage.
这篇通讯报道了利用点击化学将生物发光的雷尼拉荧光素酶蛋白与金纳米粒子(Au NPs)定点共轭,以感知蛋白酶活性。荧光素酶的生物发光被 Au NPs 有效淬灭,但在蛋白酶裂解后又显著恢复。

The present invention provides a coryneform bacterium having an ability to produce a heterologous fusion protein by secretory production, which has been modified to express a genetic construct for secretory production of the heterologous fusion protein encoding at least a heterologous fusion protein comprising an extein and an intein having an activity of acyl rearrangement. The method for producing proteins modified at the C-terminus is also provided.
