摘要:
Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Racemisierung von N-Acy laminosäuren der allgemeinen Formel (I),R-CH(NR 1 COR 2 )CO 2 H bei dem in einem Lösungsmittel ein enantiomerenangereichertes Gemisch oder eine enantiomerenreine Verbindung der Formel (I), in Gegenwart eines Übergangsmetallsalzes, Übergangsmetallkomplexes oder Übergangsmetallkomplexsalzes oder eines Gemisches davon, enthaltend mindestens ein Element aus der Gruppe Fe, Ru, Os, Co, Rh, Ir, Ni, Pd, Pt, bevorzugt bei einer Temperatur von 10 - 150 °C umgesetzt wird.
摘要:
The invention relates to a homogenous test system containing the following: (a) at least one or more, identical or different mobile nucleic acids with at least one spliceable nucleic acid, containing at least one intron; (b) at least two probes, containing corresponding fluorophores which preferably bind with the 5' and/or 3' ends of an exon/intron; (c) at least one gel-free detecting system for detecting a splicing reaction; and optionally (d) at least one composition containing splicing components; and (e) other auxiliary agents.
摘要:
The invention relates to the preparation of protein toxins from yeasts so-called killer yeasts using genetic technology in order to control human pathogenic and plant pathogenic yeasts and/or fungi, whereby these are selectively destroyed. The high specificity enables the protein toxins to be used as an antifungal agent and/or fungicide. In addition, protein toxins of this type can be used for protecting plants.
摘要:
The invention relates to complex compounds containing substituted isophosphinolines according to formula (VII) or (XIII). In general formula (VII), R means hydrogen, alkyl-, aryl-, haloaryl-, haloalkyl groups, R' means alkyl-, aryl-, haloaryl-, haloalkyl groups, R'' and R''' mean, independently of each other, hydrogen, alkyl-, aryl-, haloalkyl- or haloaryl-, alkoxy-, amino-, dialkylamino-, sulfonate groups or fluorine and two adjacent R''/R'', R''/R''' or R'''/R'''s can also be bridged, or in general formula (XIII), R' means alkyl-, aryl-, haloaryl-, haloalkyl groups, R'' and R''' mean, independently of each other, hydrogen, alkyl-, aryl-, haloalkyl- or haloaryl-, alkoxy-, amino-, dialkylamino-, sulfonate groups or fluorine and two adjacent R''/R'', R''/R''' or R'''/R''' can also be bridged and R'''' is an alkanediyl-, arenediyl- or hetarenediyl group, the term alkyl or haloalkyl group including the corresponding cyclo-compounds. The invention also relates to the use of complex compounds of this type as catalysts.
摘要:
The invention relates to a method for producing formaldehyde by non-oxidative dehydrogenation of methanol in a reactor while using a fluid catalyst. After the reactor, the product gases are brought into contact with a melt in a cooler. Said melt absorbs impurities and catalyst residues. The reactor can also serve to carry out the method, is constructed as a bubble column or countercurrent falling-film reactor, and contains a catalyst melt. The cooler is preferably constructed as a falling-film cooler.
摘要:
The invention relates to a novel polypeptide or a functional variant thereof, acting as a 5'-2,2,7 terminal trymethylguanosine(m3G-)Cap-specific receptor of nucleus import in cells, to the production and to the use thereof. The invention is preferably used as a medicament or diagnostic reagent.
摘要:
The invention relates to a nucleic acid coding for a human deadenylating nuclease (DAN) which has an amino acid sequence in accordance with SEQ 11 or one of its functional variants, and to parts thereof having at least 8 nucleotides.
