New hydroxyphenylacetaldehyde dehydrogenase, nucleic acid that codifies and vectors and recombinant microorganisms that express it (Machine-translation by Google Translate, not legally binding)

New hydroxyphenylacetaldehyde dehydrogenase, nucleic acid encoding it and vectors and recombinant microorganisms that express it. The new hydroxyphenylacetaldehyde dehydrogenase is part of a bacterial degradation pathway of tyramine and/or dopamine to pyruvic acid and succinic acid hitherto unknown. It acts after the tyramine oxidase that transforms tyramine or dopamine into 4-hydroxyphenylacetaldehyde and 3,4-dihydroxyphenylacetaldehyde, generating from them 4-hydroxyphenylacetic acid and 3,4-hydroxyphenylacetic acid, respectively. Thus, it can be used in methods directed to decrease the amount of tyramine and/or dopamine, for example in foods. The invention also relates to the nucleic acid molecules encoding the enzyme, the vectors that allow its expression and to recombinant microorganisms transformed with said vectors.

La nueva hidroxifenilacetaldehído deshidrogenasa forma parte de una vía bacteriana de degradación de tiramina y/o dopamina hasta ácido pirúvico y ácido succínico desconocida hasta ahora. Actúa tras la tiramina oxidasa que transforma tiramina o dopamina en 4-hidroxifenilacetaldehído y 3,4-dihidroxifenilacetaldehído, generando a partir de ellos ácido 4-hidroxifenilacético y 3,4-hidroxifenilacético, respectivamente. Así, puede usarse en procedimientos dirigidos a disminuir la cantidad de tiramina y/o dopamina, por ejemplo en alimentos. La invención se refiere también a las moléculas de ácido nucleico que codifican la enzima, los vectores que permitan su expresión y a microorganismos recombinantes transformados con dichos vectores.
