  Synthesis of an N-acyl sulfamate analog of luciferyl-AMP: A stable and potent inhibitor of firefly luciferase

  摘要：

  In the first of two half-reactions resulting in the emission of visible light, firefly luciferase forms luciferyl-adenylate from its natural substrates beetle luciferin and Mg-ATP. The acyl-adenylate is subsequently oxidized producing the light emitter oxyluciferin in an electronically excited state. In vitro, under mild conditions of temperature and pH, the acyl-adenylate intermediate is readily hydrolyzed and susceptible to oxidation. We report here the multi-step synthesis and physical and enzymatic characterization of an N-acyl sulfamate analog of luciferyi-adenylate, 5'-O-[(N-dehydroluciferyl)-sulfamoyl]-adenosine (compound 5). This represents the first example of a stable and potent (K-i = 340 nM) reversible inhibitor of firefly luciferase activity based on the structure of the natural acyl-adenylate intermediate. Additionally, we present the results of limited proteolysis studies that demonstrate that the binding of the novel acyl-adenylate analog protects luciferase from proteolysis. The findings presented here are interpreted in the context of the hypothesis that luciferase and the other enzymes in a large superfamily of adenylate-forming proteins adopt two conformations to catalyze two different partial reactions. We anticipate that the novel N-acyl sulfamate analog will be a valuable reagent in future studies designed to elucidate the role of conformational changes in firefly luciferase catalyzed bioluminescence.
