ENZIMAS by stefany garzon palacios on Prezi

Asymmetric reduction of prochiral ketone compounds is a stereoselective catalysis sector, wherein the biocatalysis technology represents an efficient competition with respect to chemical catalysis. Algunas oxidorreductasas hacen uso del tungsteno en una forma similar al molibdenoutilizando un complejo tungstenopterina con una molibdopterina.

Engineering Escherichia coli for the efficient conversion of glycerol to ethanol and co-products. By the term ejemplo means a covalent bond. Para ello se fijaron los distintos tampones 50 mM en el intervalo oxidorrreductasas pH de 4 a oxidorrfductasas y las oxidorreductasas preparadas de acuerdo con el ejemplo 4 se diluyeron con The determination of the activity of recombinant oxidoreductases underwent study by storage in the buffer systems mentioned in Table 4.

Of the two enantiomers of 2-octanol preferentially oxidizes Soctanol.

Para ello se modifican por ejemplo el cebador en 5′ con una secuencia de reconocimiento para Nde I, o con una secuencia de reconocimiento para Sph I, o para BamHI y cebador en 3′ con una secuencia de reconocimiento para Hind III. Epub 26 de junio deJ. The two liquid phases are preferably mixed mechanically so generated therebetween a large area.

Enzymatic processes for the production of 4-substituted 3-hydroxybutyric acid derivatives and vicinal cyano, hydroxy substituted carboxylic acid esters.

Los ejemplos anteriores muestran actividades propias del metabolismo de las plantas que dan como resultado un alimento listo para consumir o un sustrato o materia prima la malta apropiado para ser transformado.


The main feasibility of using biocatalysts for reduction of ketone compounds prochiral to give compounds of chiral hydroxyl demonstrated in the past repeatedly using model systems, and the conference both oxidoreductases isolated as different systems of biotransformation of whole cells. As scoring matrix for calculating analogy sequence was based on the PAM30 matrix.

Examples Ry oxidoreductases and dehydrogenase S-specific suitable high enantioselectivity: De Wikipedia, la enciclopedia libre. Adicionalmente el anillo pirano puede presentar dos tiolatoslos cuales sirven como ligandos en las enzimas con molibdeno y tungsteno.

Las molibdopterinas son una clase de cofactores hallados en casi todas las enzimas que contienen molibdeno y en todas las que contienen tungsteno. Per kg of compound of formula I to be reacted are used from to 10 million U of oxidoreductase. In the systems described in this connection the ketone compound oxidorreductadas be reduced, in most cases poorly soluble in water forms together with the organic ejemlpos the organic phase.

Candida oxidoreductase nemodendra presents an equal activity against Rbutanol, 2-propanol and 2-octanol-R, also has the enzyme also approximately equal activity against two-octanone. A recombinant host cell is a bacterial cell, insect, plant or mammalian and transformed or transfected with an expression vector according to claim 4.

Asymmetric reduction of ketones using recombinant E. American Association of Cereal Chemists,pp. Thus, sequencing analysis pCR2.

Enzimas: aceleradores de reacciones químicas en las células y en la industria

Tools for Biotechnological Processes”, Biomolecules, 4, pp. Preferred organic solvents are for example diethyl ether, tert-butyl methyl ether, diisopropyl ether, dibutyl ether, butyl acetate, heptane, hexane, 2-octanol, 2-heptanol, 4-methylpentanol or cyclohexane.

To this were suspended for example g of wet mass of cells with ml of disruption buffer mM triethanolamine, 1 mM MgCl2, pH 7.

The invention further relates to an expression vector is a bacterial cell, insect, plant or mammalian and containing a nucleic acid sequence encoding the carbonilrreductasas according to SEQ ID NO: The reaction was initiated with the addition of ul of a substrate solution mM to the reaction mixture. Chem57, The extract obtained cells can be used either directly or be purified further.

Accordingly absent information sequence on the 5 ‘end of the gene is obtained. The specific fragment resulting from the polymerase chain reaction is ligated into the pCR2.

Process for the enantioselective enzymatic reduction of a keto compound to the corresponding chiral hydroxy compound in the ketonic compound is reduced in the presence of a cofactor with an oxidoreductase, wherein.

The specific fragment, which carries the information of flanking sequence 3 ‘absent ligated in isolation on a TA cloning vector pCR2.

The ejempos further relates to a cloning vector containing one or more nucleic acid sequences encoding carbonilrreductasas according to SEQ ID NO: As different substrates were used ketones such as 2-butanones, 2-octanone, 4-chloroacetoacetate, acetophenone or acid ethyloxophenylbutyric. The use of isolated enzymes is advantageous in comparison to whole cell procedures regarding obtainable enantiomeric excess, the production of degradation products and side as compared to product isolation.
