The Bradyrhizobium japonicum aconitase gene (acnA) is important for free-living growth but not for an effective root nodule symbiosis.

Journal of bacteriology - 1 Nov 1996

Thöny-Meyer L, Künzler P

Abstract excerpt

The Bradyrhizobium japonicum acnA gene encoding the tricarboxylic acid cycle enzyme aconitase was cloned and characterized. The gene was mapped immediately upstream of the cytochrome c biogenesis gene cycV and found to be transcribed in the opposite direction. The nucleotide sequence of acnA was...
