    摘要: A modified luciferase protein which is a sensor for molecules including cAMP, cGMP, calcium, chelators thereof, kinases, or phosphatases is provided. Also provided is a circularly permuted anthozoan luciferase protein and a decapod crustacean luciferase protein, optionally containing one or more heterologous amino acid sequences, at least one of which directly or indirectly interacts with a molecule of interest. Further provided is a modified anthozoan luciferase protein and a decapod crustacean luciferase protein containing an insertion of one or more heterologous amino acid sequences, at least one of which directly or indirectly interacts with a molecule of interest.

    摘要: Luciferase enzymes with greatly increased thermostability, e.g., at least half lives of 2 hours at 50° C., cDNAs encoding the novel luciferases, and hosts transformed to express the luciferases, are disclosed. Methods of producing the luciferases include recursive mutagenesis. The luciferases are used in conventional methods, some employing kits.

    摘要: The present invention is directed to compositions and methods for single-step extraction and detection of ATP levels from microbial cells. The disclosed compositions are formulated to efficiently elicit bioluminescent detection of ATP among a broad variety of different microorganisms using a common single-step reagent composition. Additional luminescence-based methods are provided for identifying other useful extracting agents or for screening compounds for their pharmaceutical or biological effects on microbial cells.

    摘要: The invention provides active, non-naturally occurring mutants of beetle luciferases and DNAs which encode such mutants. A mutant luciferase of the invention differs from the corresponding wild-type luciferase by producing bioluminescence with a wavelength of peak intensity that differs by at least 1 nm from the wavelength of peak intensity of the bioluminescence produced by the wild-type enzyme. The mutant luciferases and DNAs of the invention are employed in various biosensing applications.
