Protein

Nitrogen fixation regulation protein FixK

Gene

fixK

Organism
Bradyrhizobium diazoefficiens (strain JCM 10833 / IAM 13628 / NBRC 14792 / USDA 110)
Status
Reviewed - Annotation score: 2 out of 5- Experimental evidence at transcript leveli

Functioni

B.japonicum has two FixLJ-dependent FixK homologs that are activators of the transcription of a group of genes involved in anaerobic processes such as denitrification and possibly nitrogen fixation. FixK may bind DNA at the FNR consensus binding site.
