Bi-directional selection markers with improved activity










Image Number 3 for United States Patent #7951568.

The present invention discloses a polypeptide selected from the group consisting of: a polypeptide having an amino acid sequence according to SEQ ID NO 3, a polypeptide having an amino acid sequence according to SEQ ID NO 6, a polypeptide having an amino acid that is substantially homologous to the sequence of SEQ ID NO 3 and a polypeptide having an amino acid that is substantially homologous to the sequence of SEQ ID NO 6, the polypeptide displaying acetamidase activity and providing a reverse selection on fluoroacetamide with an efficiency of at least 95%, preferably at least 96%, more preferably at least 97%, more preferably at least 98%, more preferably at least 99%, most preferably 100%. The gene encoding the polypeptide of the invention is used as an efficient bi-directional selection marker in the construction of selection marker free strains, in particular for processes for the production of a compound of interest.
