Design and Control of Extrachromosomal Elements in Methylorubrum extorquens AM1.

ABSTRACT: Genetic tools are a prerequisite to engineer cellular factories for synthetic biology and biotechnology. Methylorubrum extorquens AM1 is an important platform organism of a future C₁-bioeconomy. However, its application is currently limited by the availability of genetic tools. Here we systematically tested repABC regions to maintain extrachromosomal DNA in M. extorquens. We used three elements to construct mini-chromosomes that are stably inherited at single copy number and can be shuttled between Escherichia coli and M. extorquens. These mini-chromosomes are compatible among each other and with high-copy number plasmids of M. extorquens. We also developed a set of inducible promoters of wide expression range, reaching levels exceeding
