Title
(EN) GENE EXPRESSION SYSTEM FOR PROBIOTIC MICROORGANISMS
(FR) SYSTÈME D'EXPRESSION GÉNIQUE POUR MICROORGANISMES PROBIOTIQUES
Abstract
(EN)
Provided herein are recombinant microorganisms that express a subject polypeptide. Microorganisms can comprise an expression construct comprising a flagellin promoter operatively linked with a heterologous nucleotide sequence encoding the subject polypeptide. The flagellin promoter sequence can comprise a genetic modification that reduces CsrA inhibition of translation. Microorganisms also can comprise a genetic modification that reduces FlgM inhibition of SigD initiation of transcription. The target polypeptide can be an aldehyde dehydrogenase. Such microorganisms are useful in the treatment of alcohol hangover.
(FR)
L'invention concerne des microorganismes recombinés qui expriment un polypeptide sujet. Les microorganismes peuvent comprendre une construction d'expression comprenant un promoteur de flagelline fonctionnellement lié à une séquence nucléotidique hétérologue codant le polypeptide sujet. La séquence de promoteur de flagelline peut comprendre une modification génétique qui réduit l'inhibition de la traduction par CsrA. Les microorganismes peuvent également comprendre une modification génétique qui réduit l'inhibition par FlgM de l'initiation de la transcription de SigD. Le polypeptide cible peut être une aldéhyde déshydrogénase. Ces microorganismes sont utiles dans le traitement de la xylostomiase due à l'alcool.
