The present invention pertains to an isolated P450 enzyme comprising or consisting of an amino acid sequence at least 80% identical to SEQ ID NO: 1, wherein said sequence comprises a threonine at position corresponding to position 225 and/or an aspartic acid mutation at position corresponding to position 289. The invention also concerns an isolated nucleic acid comprising a sequence encoding said enzyme, a vector comprising said nucleic acid, and a host cell containing said nucleic acid or said vector. Methods for preparing said enzyme and methods for producing steroid hormone precursors using the enzyme or the host cells featured in the invention are also provided.

A method for producing a microbial oil includes steps of: genetically modifying a labyrinthulid by disrupting and/or silencing a gene, or by transforming another gene in addition to the disruption and/or gene silencing of the gene, and culturing the labyrinthulid, such that a fatty acid composition accumulated in the labyrinthulid comprises an increased EPA content; and collecting the microbial oil having the increased EPA content from the labyrinthulid. The labyrinthulid before the modification is selected from (A) a labyrinthulid belonging to the genus Parietichytrium or genus Schizochytrium and having very weak or no activity of producing PUFAs via a PUFA-PKS pathway; and (B) a labyrinthulid belonging to the genus Thraustochytrium in which a host PUFA-PKS gene is disrupted or silenced to a very weak level. The increased EPA content is preferably not less than 11.5% of a total fatty acid composition.

Disclosed are lysine specific histone demethylase-1 (LSD1) inhibitors in methods and compositions for immune check-point inhibition. The invention also relates to proteinaceous molecules and their use in altering at least one of (i) formation, (ii) 5 N proliferation, (iii) maintenance, (iv) epithelial to mesenchymal cell transition (EMT), or (v) mesenchymal to epithelial cell transition (MET) of an LSD1 overexpressing cell.

The present invention relates to a recombinant microorganism which is modified to be capable of producing diosmin and hesperidin and to the use thereof for producing diosmin and/or hesperidin.

This invention relates in part to plant breeding and herbicide tolerant plants. This invention includes a novel AAD-1 transformation event in corn plants comprising a polynucleotide sequence, as described herein, inserted into a specific site within the genome of a corn cell. In some embodiments, said event/polynucleotide sequence can be “stacked” with other traits, including, for example, other herbicide tolerance gene(s) and/or insect-inhibitory proteins. Additionally, the subject invention provides assays for detecting the presence of the subject event in a sample (or corn grain, for example). The assays can be based on the DNA sequence of the recombinant construct, inserted into the corn genome, and on the genomic sequences flanking the insertion site. Kits and conditions useful in conducting the assays are also provided.

A method of demethylizing an opioid to a nor-opioid is provided. The method comprises contacting an opioid with at least one enzyme. Contacting the opioid with the at least one enzyme converts the opioid to a nor-opioid. A method of converting a nor-opioid to a nal-opioid is provided. The method comprises contacting a nor-opioid with at least one enzyme. Contacting the nor-opioid with the at least one enzyme converts the nor-opioid to a nal-opioid.

Recombiant microorganisms, plants, and plant cells are disclosed that have been engineered to express recombinant genes encoding UDP-glycosyltransferases (UGTs). Such microorgansims, plants, or plant cells can produce steviol glycosides, e.g., Rebaudioside A and/or Rebaudioside D, which can be used as natural sweeteners in food products and dietary supplements.

Described in this application are enzymes (e.g., cucurbitadienol synthases (CDS), UDP-glycosyltransferases (UGT), C11 hydroxylases, epoxide hydrolases (EPH), squalene epoxidases, and/or cytochrome P450 reductases), host cells expressing the enzymes, and methods of producing mogrol precursors, mogrol, and/or mogrosides using such host cells.

The present invention relates generally to production methods, enzymes and recombinant yeast strains for the biosynthesis of clinically important prenylated polyketides of the cannabinoid family. Using readily available starting materials, heterologous enzymes are used to direct cannabinoid biosynthesis in yeast.

The present invention provides for methods of epigenetic analysis. In some cases, the methods may include obtaining a sample comprising a nucleic acid sequence. In some cases, the nucleic acid sequence may comprise one or more epigenetic marks. The methods may include performing a sequencing. The methods may include distinguishing a hydroxymethylated base from a methylated base.
