Regulatory response to a hybrid ancestral nitrogenase in Azotobacter vinelandii

open access: yesMicrobiology Spectrum, 2023
Biological nitrogen fixation, the microbial reduction of atmospheric nitrogen to bioavailable ammonia, represents both a major limitation on biological productivity and a highly desirable engineering target for synthetic biology. However, the engineering
