Recombinant microorganism for producing L-valine, construction method and application thereof
Related are a recombinant microorganism for producing L-valine, a construction method and an application thereof. Through transferring an acetohydroxy acid reductoisomerase gene and/or an amino acid dehydrogenase gene into a microorganism, and enhancing activity of an acetohydroxy acid reductoisomerase and/or an amino acid dehydrogenase, the titer and yield of L-valine generated by Escherichia coli may be improved, and L-valine was produced by one-step anaerobic fermentation.
FLAVONOID AND ANTHOCYANIN BIOPRODUCTION USING MICROORGANISM HOSTS
The invention is directed to methods involved in the production of flavonoids, anthocyanins and other organic compounds. The invention provides cells engineered for the production of flavonoids, anthocyanins and other organic compounds, where the engineered cells include one or more genetic modifications that increase flavonoid production by increasing metabolic flux to flavonoid precursors and/or reducing carbon losses resulting from the production of byproducts.
SYNTHETIC QUORUM-REGULATED LYSIS
Provided are bacterial strains, methods of culturing bacterial cells using synthetic quorum-regulated lysis, and uses thereof.
MODIFIED TRANSGLUTAMINASE
The present invention addresses the issues of finding a novel mutation effective for the improvement of transglutaminase and providing a highly useful modified transglutaminase. Disclosed is a highly useful modified transglutaminase having an amino acid substitution that results in an increase of high temperature reactivity or a lowering in pH stability in a weakly acidic region.
DAIRY-LIKE COMPOSITIONS AND RELATED METHODS
Provided herein are dairy-like analogue compositions and the methods of making the same using one or more recombinant proteins.
ONE-STEP METHOD FOR PRODUCING ADENOVIRAL VECTORS
The disclosure is directed to a gene transfer vector which comprises (i) all or part of a viral genome and (ii) a suicide gene flanked by unique cloning sequences. The disclosure also is directed to a system for producing an adenoviral vector comprising a destination vector comprising (i) all or part of an adenoviral genome and (ii) a suicide gene flanked by unique cloning sequences; a transgene flanked by unique cloning sequences; and (c) reagents for Gibson DNA Assembly (GDA). A method of producing an adenoviral vector using the aforementioned system also is provided.
cAMP receptor protein variant, coding sequence and method of producing L-amino acid using the same
Provided are a cAMP receptor protein variant and coding sequence, a microorganism including the same, and a method of producing a L-amino acid using the same.
DOWNSCALING PARAMETERS TO DESIGN EXPERIMENTS AND PLATE MODELS FOR MICRO-ORGANISMS AT SMALL SCALE TO IMPROVE PREDICTION OF PERFORMANCE AT LARGER SCALE
Systems, methods and computer-readable media are provided for designing experiments for organisms at a first scale to generate first-scale performance data used in predicting performance of the organisms at a second, larger scale. The design includes determining first-scale screening conditions based at least in part upon the contribution of second-scale conditions to performance parameters of an organism at the second scale. The first-scale screening conditions include one or more proxies for second-scale conditions that cannot be replicated at first scale. The design determines first-scale screening parameters based at least in part upon computer modeling of the metabolism of the organism at the second scale.
ESCHERICHIA COLI-BASED RECOMBINANT STRAIN, CONSTRUCTION METHOD THEREFOR AND USE THEREOF
An Escherichia coli-based kdtA-gene-modified recombinant strain, a construction method therefor and use thereof are provided. A mutant gene obtained by subjecting a wild-type kdtA gene (ORF sequence is shown in a sequence 73556-74833 in GenBank accession No. CP032667.1), a wild-type spoT gene (ORF sequence is shown in a sequence 3815907-3818015 in GenBank accession No. AP009048.1) and a wild-type yebN gene (ORF sequence is shown in a sequence 1907402-1907968 in GenBank accession No. AP009048.1) of an E. coli K12 strain and a derivative strain thereof (such as MG1655 and W3110) to site-directed mutagenesis, and a recombinant strain obtained therefrom can be used for the production of L-threonine. Compared with an unmutated wild-type strain, the obtained strain can produce L-threonine with a higher concentration and has good strain stability, and also has lower production cost as an L-threonine production strain.
BIOSYNTHESIS OF ERIODICTYOL
The present invention relates to methods and transformed host cells for the production of eriodictyol from naringenin via bioconversion.
