METHOD FOR THE PRODUCTION OF A LYSATE USED FOR CELL-FREE PROTEIN BIOSYNTHESES

摘要

The invention relates to a method for producing a lysate used for cell-fee protein biosynthesis, comprising the following steps: a) a genomic sequence in an organism, which codes for an essential translation product that reduces the yield of cell-fee protein biosynthesis, is replaced by the foreign DNA located under a suitable regulatory element, said foreign DNA coding for the essential translation product that additionally contains a marker sequence; b) the organism cloned according to step a) is cultivated; c) the organisms from the culture obtained in step b) are lysed; and d) the essential translation product is eliminated by means of a separation process that is selective for the marker sequence. Also discussed are said lysate and the use thereof
