摘要:
The invention relates to a nucleic acid construct for detecting a compound comprising a coding region and a regulatory element, which controls expression of the coding region depending on the compound and to a cell comprising such a construct. In addition, the invention relates to a method for detecting a compound in a sample. The invention further relates to a biosensor for detecting a compound comprising an electrode system, a device for measuring electron transfer in the electrode system, and a microorganism.

The problem to be resolved is to provide an electron mediator and a fusion body with high affinity with an enzyme, a measuring method using extracellular secretion type cytochrome and an enzyme, an electrode, and a sensor. The present invention relates to an electron mediator for glucose oxidoreductase comprising extracellular secretion type cytochrome, a fusion body in which the electron mediator is fused with glucose oxidoreductase, a composition for glucose measurement including the electron mediator or fusion body, a gene encoding a new extracellular secretion type cytochrome, and a measurement method using extracellular secretion type cytochrome and an enzyme, an electrode, and a sensor.

The present invention relates to cupredoxin and cytochrome and their use, separately or together, to inhibit the spread of parasitemia in mammalian red blood cells and other tissues infected by the malaria parasite, and in particular the parasitemia of human red blood cells by P. falciparum. The invention provides isolated peptides that are variants, derivatives or structural equivalents of cupredoxins or cytochrome c, and compositions comprising cupredoxins and/or cytochrome c, or variants, derivatives or structural equivalents thereof, that are useful for treating or preventing malaria infection in mammals. Further, the invention provides methods to treat mammalian patients to prevent or inhibit the growth of malarial infection in mammals. The invention also provides methods to prevent the growth of malaria infection in insect vectors.

Modulation of cytochrome c acetylation, e.g., with a SIR polypeptide, enables interventions that modulate lifespan regulation and cell proliferation, e.g., by modulating apoptosis and/or mitochondrial function such as respiration.

The invention is directed to methods and compositions for chemical ligation of components comprising a first component having a carboxythioester, and preferable an alpha -carboxythioester, moiety and a second component having an N-substituted, and preferably an N alpha -substituted, 2 or 3 carbon chain alkyl or aryl thiol to give a ligation product having an N-substituted amide bond at the ligation site. The reactants of the invention are chemoselective, and the alkyl or aryl thiol moiety is removable from the ligation product. Removal of the alkyl or aryl thiol gives a native amide bond at the ligation site. The methods and compositions of the invention are particularly useful for ligation of peptides and polypeptides. The ligation system of the invention is applicable to a wide variety of molecules, and thus can be exploited to generate peptides, polypeptides and other amino acid containing polymers having a native amide bond at the ligation site.

Cytotoxic factors having use in modulating cell death, and their use in methods of treating necrosis or apoptosis-related conditions are disclosed. The invention also relates to methods for identifying active agents useful in treating conditions related to cell death or uncontrolled growth. The present inventors have found that different microorganisms produce different cylotoxic factor(s) having anticancer activity. The substantially pure cytotoxic factors can be used in a method of treating an infectious disease or a cancer.
摘要:
La présente invention a pour objet une souche de levure dans les chromosomes de laquelle sont intégrés de façon stable plusieurs gènes hétérologues et permettant leur expression caractérisée en ce que: (1) la souche de levure est une souche diploïde dont les allèles sont totalement isogéniques à l'exception des loci qui portent les gènes hétérologues et du locus sexuel, (2) les loci hétérozygotes sont dépourvus d'allèles portant un gène sauvage, (3) les gènes hétérologues sont placés sous le contrôle d'un promoteur inductible et régulable.
