A gene cluster of the ochratoxin A biosynthetic genes inPenicillium
Mycotoxin Research, 2006A putative ochratoxin A (OTA) biosynthetic gene cluster inP. nordicum has been identified. The first part of the gene cluster is located on a DNA fragment of 10 kb in length and harbours three genes. A gene with high homology to an alkaline serine protease gene (accession number AY557343), which represents the upstream border of the cluster ...

Nat. Prod. Rep., 2011
Ergot alkaloids are toxins and important pharmaceuticals which are produced biotechnologically on an industrial scale. They have been identified in two orders of fungi and three families of higher plants. The most important producers are fungi of the genera Claviceps, Penicillium and Aspergillus (all belonging to the Ascomycota).

Targeting Trichothecene Biosynthetic Genes
2016Biosynthesis of trichothecenes requires the involvement of at least 15 genes, most of which have been targeted for PCR. Qualitative PCRs are used to assign chemotypes to individual isolates, e.g., the capacity to produce type A and/or type B trichothecenes. Many regions in the core cluster (consisting of 12 genes) including intergenic regions have been

Regulation of epidermin biosynthetic genes by EpiQ
Molecular Microbiology, 1993SummaryWe investigated the role of epiQ in the biosynthesis of the lantibiotic epidermin. epiQ was essential for epidermin production. It was shown that EpiQ controls epidermin production by transcriptionally activating the epiA promoter, used for transcription of most of the epidermin biosynthetic genes.

Characterization of the Actinonin Biosynthetic Gene Cluster
ChemBioChem, 2018AbstractThe hydroxamate moiety of the natural product actinonin mediates inhibition of metalloproteinases because of its chelating properties towards divalent cations in the active site of those enzymes. Owing to its antimicrobial activity, actinonin has served as a lead compound for the development of new antibiotic drug candidates.

Targeting Ochratoxin Biosynthetic Genes
2016The pathway of ochratoxin A (OTA) biosynthesis has not yet been completely elucidated. Essentially, two kind of genes have been demonstrated to be involved in the biosynthesis of OTA. One of them is the nrps gene encoding a non-ribosomal peptide synthetase (NRPS) which catalyzes the ligation between the isocoumarin group, constituting the polyketide ...

Biosynthetic retrovectoring systems for gene therapy
Journal of Molecular Medicine, 1997Chemical and physical methods of introducing genes into cells (transfection) are being combined with viral transduction as one possible approach toward overcoming the shortcomings of current gene transfer methods. Although several different strategies are being developed worldwide, this article focuses on modification of retroviral vectoring systems ...

Targeting Aflatoxin Biosynthetic Genes
2016Chemical detoxification and physical destruction of aflatoxins in foods and feed commodities are mostly unattainable in a way that preserves the edibility of the food. Therefore, preventing mycotoxins in general and aflatoxins in particular from entering the food chain is a better approach.

Targeting Fumonisin Biosynthetic Genes
2016The fungus Fusarium is an agricultural problem because it can cause disease on most crop plants and can contaminate crops with mycotoxins. There is considerable variation in the presence/absence and genomic location of gene clusters responsible for synthesis of mycotoxins and other secondary metabolites among species of Fusarium.
