"The oxygen paradox" is a problem discovered in the last century in the biological nitrogen fixation process. This effect seriously restricts the efficiency of biological nitrogen fixation.

The symbiotic nitrogen fixation of legumes and rhizobia solves this problem, thus fixing 50-70 million tons of nitrogen per year, contributing 60% of the total biological nitrogen fixation.

So that it can ensure the normal aerobic breathe and let oxygen not affect the oxygen-sensitive enzyme, enabling the bacteria doing nitrogen fixation simultaneously.

Whereas, the problem of the antagonism between the oxidation process and the reduction process as the "oxygen paradox" is widely present in many organisms and in many biochemical reaction processes.

A series of globins (respiratory proteins) with different efficiencies such as leghemoglobin can be found and constructed as a set of genetic tools that can achieve different degrees of low oxygen concentration requirements to meet various reducing biochemical reactions. This is our project -- "Oxygen Hunter".
