摘要: The present disclosure provides recombinant microorganisms and methods for the production of 4-HMF, 2,4-furandimethanol, furan-2,4-dicarbaldehyde, 4-(hydroxymethyl)furoic acid, 2-formylfuran-4-carboxylate, 4-formylfuran-2-carboxylate, and/or 2,4-FDCA from a carbon source. The method provides for engineered microorganisms that express endogenous and/or exogenous nucleic acid molecules that catalyze the conversion of a carbon source into 4-HMF, 2,4-furandimethanol, furan-2,4-dicarbaldehyde, 4-(hydroxymethyl)furoic acid, 2-formylfuran-4-carboxylate, 4-formylfuran-2-carboxylate, and/or 2,4-FDCA. The disclosure further provides methods of producing polymers derived from 4-HMF, 2,4-furandimethanol, furan-2,4-dicarbaldehyde, 4-(hydroxymethyl)furoic acid, 2-formylfuran-4-carboxylate, 4-formylfuran-2-carboxylate, and/or 2,4-FDCA.

摘要: The present disclosure relates generally to methods and cell lines for the production of phytocannabinoids, phytocannabinoid precursors or intermediates, or phytocannabinoid analogue. Methods for transformation of host cells, such as yeast cells, are described. Cells may be transformed, for example, with a polynucleotide encoding a polyketide synthase (PKS) enzyme, a polynucleotide encoding an olivetolic acid cyclase (OAC) enzyme, and/or a polynucleotide encoding a prenyltransferase (PT) enzyme; and optionally a polynucleotide encoding an acyl-CoA synthase (Alk) enzyme; a polynucleotide encoding a fatty acyl CoA activating (CsAAE) enzyme; and/or a polynucleotide encoding a THCa synthase (OXC) enzyme.

摘要: Disclosed is a method for resolving an optical isomer from a racemate by means of electrodialysis. Specifically, an electrodialysis technique is used in an enzymatic resolution process, mainly in the separation of products after enzymatic resolution. Taking a preparation process for D-pantolactone as an example, the key point is that D-pantoic acid and L-pantolactone are separated from an enzymatic resolution solution by means of an electrodialysis method, which replaces the existing organic solvent extraction method. The process method is simple and easy to operate, has a high yield of D-pantoic acid of a good purity, greatly reduces the usage amount of an organic solvent, reduces production costs and is environmentally friendly, such that the working environment of workers can be improved to a great extent, and the operation safety index is improved.

摘要: The problem to be solved by the present invention is to provide a method of producing isoprenoids including ascofuranone, ilicicolin A, and ascochlorin and derivatives thereof in a high yield as compared to the conventional art, which method enables industrial-scale production of isoprenoids. The problem can be solved by a method of producing isoprenoids such as ascofuranone, ilicicolin A, and ascochlorin, including using a transformant obtained by transformation with biosynthetic genes for ascofuranone, ilicicolin A, or ascochlorin or a knockout organism for these genes to obtain isoprenoids such as ascofuranone, ilicicolin A, and ascochlorin.

摘要: The present invention provides a Diels-Alderase and use thereof, and belongs to the field of gene engineering technology. The Diels-Alderase is MaDA, and its amino acid sequence and gene sequence are represented by SEQ ID Nos. 1 and 2, respectively. The present invention also provides MaDA-1 and MaDA-2, both of which are homologous proteins of MaDA, and their amino acid sequences are represented by SEQ ID Nos. 10 and 12, respectively. The present invention has discovered that MaDA and its homologous proteins from Morus alba can stereospecifically synthesize natural products of endo configuration, and prepare D-A type natural products and their analogs in vitro using chalcones and dehydroprenyl-containing compounds as substrates, which helps to develop and utilize the medicinal value of such natural products, and also provides a possibility to synthesize other six-membered ring-containing important chemical precursors or natural products.

摘要: Provided herein are biocatalytic methods of producing terpene compounds by applying a novel type of phosphatase enzyme. The method allows the fully biochemical synthesis of terpene compounds, like for example copalol and labdendiol, and derivatives thereof, which serve as valuable intermediates for the production of perfumery ingredients, such as, for example, ambrox. Also provided are novel fully biochemical multistep processes for the production of such compounds as well as novel phosphatase enzymes and mutants and variants derived therefrom.
