Export and modification of (poly)peptides in the lantibiotic way

   
   

The invention includes a method for harvesting a polypeptide produced by a host cell, wherein the polypeptide has not undergone intracellular posttranslational modification, such as dehydration of a serine or a threonine, and/or thioether bridge formation. The invention also includes a method for producing thioether-containing peptides and dehydroalanine/dehydrobutyrine-containing.peptides, wherein thioether rings may be formed extracellularly.

La invención incluye un método para cosechar un polipéptido producido por una célula huesped, en donde el polipéptido no ha experimentado la modificación intracelular del posttranslational, tal como deshidratación de un serine o de un threonine, y/o la formación del puente del thioether. La invención también incluye un método para producir los peptides thioether-que contienen y dehydroalanine/dehydrobutyrine-containing.peptides, en donde los anillos del thioether se pueden formar extracellularly.
