A microorganism which is genetically modified so that it produces a first essential biomass precursor by metabolizing CO.sub.2 using a recombinant carbon fixation enzyme is disclosed. The microorganism produces a second biomass precursor by metabolizing an organic carbon source and not by metabolizing CO.sub.2. The microorganism does not use the organic carbon source for producing the first essential biomass precursor.

The present disclosure provides for methods of treating or preventing a cardiovascular disorder and/or a related pulmonary disorder in a subject. In certain embodiments, a therapeutically effective amount of a polynucleotide inhibitor of Glucose-6-phosphate dehydrogenase (G6PD) or a nucleic acid encoding G6PD is administered.

Homogeneous immunoassays that allow for compensation of background signals inherent in samples and reagents. The use of homogeneous immunoassays for the detection of the presence or amount of symmetrical Dimethyl Arginine (SDMA) in biological samples. Reagents and kits for conducting the assays.

The present invention relates to multi-hapten mutant G6PDH conjugates, methods of their preparation and their use for detection of multiple analytes. The compositions of the invention comprise different types of haptens (molecules) require to be immobilized into the G6PDH to make one multi-hapten-G6PDH conjugate. Both thiol and amine functional groups on G6PDH are utilized for immobilization of different haptens.

A reagent for glutamine synthetase reaction comprising a chelating agent and glutamine synthetase, and a reagent for quantification of ammonia comprising a chelating agent, ATP, glutamic acid, glutamine synthetase, glucose, an oxidized NAD compound, ADP-dependent hexokinase, and glucose-6-phosphate dehydrogenase, are provided.

The present invention relates to a method for constructing a recombinant bacterium with high production of ?-elemene and germacrene A. Firstly, ?-elemene and germacrene A are synthesized from scratch through the screening of germacrene A synthase and the overexpression of the mevalonate pathway; then, the availability of acetyl-CoA, pyruvate, and glyceraldehyde-3-phosphate in the farnesyl diphosphate pathway is ensured by deleting competing pathways in the central carbon metabolism; next, the present invention uses lycopene color as a high-throughput screening method and obtains an optimized NSY305N through error-prone PCR. Finally, in shake flasks, strain ?-EL-4 constructed through key pathway enzymes, efflux engineering, and translation engineering produced 1161.09 mg/L of ?-elemene and 852.36 mg/L of germacrene A, which is the highest reported yield at shake flask level. In 4-L fed-batch fermentation, the production of ?-elemene and germacrene A reached 3.52 g/L and 2.13 g/L, respectively.

Compounds and methods for use in detecting pregabalin in a sample suspected of containing pregabalin are disclosed. Pregabalin derivatives are described for producing pregabalin conjugates. A pregabalin-immunogenic carrier conjugate may be used as an immunogen for the preparation of an anti-pregabalin antibody. A pregabalin-detectable label conjugate may be used in a signal producing system in pregabalin assays.

The present invention relates to a eukaryotic cell that is genetically modified comprising one or more heterologous gene encoding: a) D-glucose-6-phosphate dehydrogenase and/or b) 6-phosphogluconate dehydrogenase; and/or c) glucose dehydrogenase, gluconolactonase and gluconate kinase,
wherein a), b) and glucose dehydrogenase in c) are NAD.sup.+ dependent.

Provided is a genetically engineered yeast cell having increased NADPH production, a method of increasing a NADPH level in a yeast cell, a method of preparing the genetically engineered yeast cell, and a method of producing lactate using the genetically engineered yeast cell.
