Abstract

An artificial non-coding RNA (ncRNA) module constructed by a synthetic biology technique and the use of the artificial ncRNA module in the construction of an artificial nitrogen fixation system are disclosed. The RNA module can enhance the post-transcriptional stability of nifHDK mRNA by interacting with a nitrogenase coding gene nifHDK mRNA, thereby improving the nitrogen fixation ability of a chassis microorganism. A fusion expression vector carrying the artificial RNA module is constructed and transformed into different chassis nitrogen-fixing microorganisms. It is confirmed through experiments that, under nitrogen fixation conditions, the artificial RNA module of the present disclosure can significantly improve the nitrogenase activity of a recombinant engineering bacterial strain.
