Nos Z gene from P. stutzeri

This is the Nitrous Oxide Reductase gene from Pseudomonas stutzeri codon optimized for expression in Chlamydomonas reinhardtii. Nitrous oxide reductase is responsible for the reduction of nitrous oxide (N₂O) into water and dinitrogen (N₂) by acting as the catalysis of a copper-dependent two-electron reduction of N₂O [1]. This ensures that a bacterial host will not have a truncated nitrogen pathway, and will put harmless N₂ in the atmosphere instead of the greenhouse gas N₂O. Additionally, we hope this will cause the transformed host to uptake more nitrogen from its environment.

Verification of nosZ P. stu

Successful transformation of pL0-P.stu into host bacterium can be determined by a restriction digest with the restriction enzyme BbsI, with the molecular weights being 1914bp and 2088bp. Additionally, bacterial colonies should appear white in the present X-gal.
