El sustrato que es oxidado es considerado donador de Hidrgeno. El nombre sistemtico est basado en la oxidorreductasa donadora:aceptora. El nombre recomendado es deshidrogenasa, siempre que sea posible. Como alternativa puede usarse reductasa.

Nasida Enzymatic reduction itself takes place in mild conditions, so that the alcohols do not react subsequently generated. Ha dirigido 31 Tesis de Licenciatura y 13 de Posgrado.

Asymmetric reduction of ketones using recombinant E. The enantiomeric excess is calculated as follows: The extract obtained cells can be used either directly or be purified further. En la Tabla 1 se muestran algunos ejemplos de enzimas y sus aplicaciones en alimentos. It is also not possible using whole cell processes in any chemical company, because for that special equipment and expertise are needed.

Cloning and fjemplos of the oxiforreductasas yellow enzyme gene of Candida macedoniensis, and its application to the production of a chiral compound. Development of a combined biological and chemical process for production of industrial aromatics from renewable resources. Los cosustratos adecuados de la formiato Suitable cosubstrates of formate. Los restos arilo C6-C14 son por ejemplo fenilo, naftilo, por ejemplo 1-naftilo, 2-naftilo, bifenililo, por ejemplo 2-bifenililo, 3bifenililo y 4-bifenililo, antrilo o fluorenilo.

The aryl C6-C14 are for example phenyl, naphthyl, for example 1-naphthyl, 2-naphthyl, biphenylyl, for example 2-biphenylyl, 4-biphenylyl 3bifenililo and, anthryl or fluorenyl. 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.

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. La molibdopterina de hecho es un derivado de piranopterina, un heterociclo complejo que presenta un pirano unido a un anillo pterina. Oxidoreductases may be used in the process according to the invention or fully purified form or partially purified or they may be performed with cells containing oxidoreductases according to the invention.

Compositions and methods for producing stereoisomerically pure ejemlos and synthetic intermediates therefor. Enzymatic processes for the production of 4-substituted 3-hydroxybutyric acid derivatives and vicinal cyano, hydroxy substituted carboxylic acid esters. Los modelos de sitio activo para las enzimas que contienen molibdopterina, se encuentran basados en una clase de ligandos conocidos como ditiolenos.

De Wikipedia, la enciclopedia libre. This solvent is for example a dialkyl C1-C6 symmetrical or asymmetrical ether, a straight or branched alkane or cycloalkane chain or secondary alcohol insoluble in water, which in turn represents the cosubstrate.

To determine the pH optimum for the oxidation reaction is used as cofactor NAD P and as substrate 2-propanol or 2-octanol. The invention further relates to novel oxidoreductases for use in the enantioselective reduction of keto compounds to give compounds of chiral hydroxyl. The coenzyme regeneration is made in this respect by the simultaneous oxidation of secondary alcohols, being used ejfmplos most cases the 2-propanol miscible with water, economic.

Ketoreductase polypeptides for the production of 3-arylhydroxypropanamine from a 3-arylketopropanamine. 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.

The resulting nucleic acid served as a matrix for the polymerase chain reaction PCR with degenerate primers. A recombinant host cell is a bacterial cell, insect, plant or mammalian and transformed or transfected with an expression vector according to claim 4.

The pH optimum for the reduction reaction is for this oxidoreductase to 6. Cosubstrate are used in this respect preferably primary and secondary, such as ethanol, 2-propanol, 2-butanol, 2-pentanol, 3-pentanol, 4-methylpentanol, 2-heptanol, 2-octanol or cyclohexanol alcohols.
