Strain variation in bacteriocuprein superoxide dismutase from symbiotic Photobacterium leiognathi.

abstract：:An increased demand for cytochromes is associated with symbiotic development and microaerobic metabolism in the bacterium Bradyrhizobium japonicum, and evidence suggests that hemB, rather than hemA, is the first essential bacterial heme synthesis gene in symbiosis with soybean. Steady-state levels of mRNA and protein ...
