Abstract:
The invention relates to proteins that have an enzymatic activity for reducing substituted alkanones, such as 3-methylamino-1-(2-thienyl)-propane-1-on. The invention also relates to nucleic acids that encode these proteins, to nucleic acid constructs, vectors, genetically modified microorganisms and to methods for producing substituted (S) alkanols, such as for example (S)-3-methylamino-1-(2-thienyl)-(S)-propanol.
Abstract:
The invention relates to novel polynucleotides obtained from Ashbya gossypii, to oligonucleotides that hybridise with the latter, to expression cassettes and vectors containing said polynucleotides, to micro-organisms transformed therewith, to polypeptides that have been coded by said polynucleotides and to the use of the novel polypeptides and polynucleotides as targets for modulating the control of transcription and/or translation and/or the control of RNA processing and in particular the improvement of vitamin B2 production in micro-organisms of the genus Ashbya.
Abstract:
The invention relates to novel nucleic acid molecules and polypeptides encoded thereby, which may be used for identification or classification of Ashbya gossypii or related types of micro-organisms.
Abstract:
A gene is disclosed which contains the nucleotide sequence represented by SE ID NO:1 and which extends from nucleotide 671 to nucleotide 6295, or a nucleotide sequence derived therefrom by substitution, insertion or deletion of up to 30 %, 20 %, 10 % or 5 % of its nucleotides, the lower percentages being preferable, and whose genetic product exhibits the enzymatic activity of an adenylate cyclase. Also disclosed is its use.
Abstract:
The present invention relates to inhibition of GTP cyclohydrolase II as target for the identification of fungicides. Binding assays are claimed and coupled enzymatic assays are disclosed involving the conversion of formate (product of the reaction catalyzed by GTP-cyclohydrolases) by formate dehydrogenase and spectroscopically measuring the NADH formed. Furthermore in vivo assays with organisms containing a GTP-cyclohydrolase II are claimed as well as a DNA sequence for a fungal GTP-cyclohydrolase II. 3-Butyl-10-(3-chlorophenyl)- 10H-pyrimido[4,5-b]quinoline-2,4-dione is identified by the enzymatic method as a fungicide. Finally, methods of controlling fungi (e.g. on plants, in soil) by applying this agent are claimed.
Abstract:
The invention relates to novel nucleic acid molecules and polypeptides coded by the same which can be used for identifying or classifying Ashbya gossypii or related species of fungus.
Abstract:
The invention relates to a genetic method for producing riboflavin. The production of riboflavin in organisms is increased by specially selecting genes of the riboflavin biosynthesis or of the combination thereof in organisms, especially in bacteria, fungi, yeasts and plants, and of the expression thereof. The invention also relates to a nucleic acid fragment containing genes with the sequences SEQ ID No. 1, SEQ ID No. 3 or SEQ ID No. 5 or the functional equivalents thereof, to expression vectors containing the nucleic acid fragments, and to organisms containing at least one nucleic acid fragment or at least one vector.
Abstract:
The invention relates to animal food additives containing a vitamin B6, a method for producing said additives, animal food compounds containing the inventive additive and a method for introducing said additives into the animal food compounds.
Abstract:
The invention relates to nucleic acid molecules and polypeptides coded by the same which can be used for identifying or classifying Ashbya gossypii or related species of micro-organisms.
Abstract:
The invention relates to a monocellular or multicellular organism, especially a microorganism, for biotechnological production of riboflavin, whereby the enzymatic activity thereof with respect to NAD(P)H formation is higher than that of a wild type of species Ashbya gossypii ATCC10895.
