Abstract
Nitrogen fixation-associated genes in Bradyrhizobium japonicum are controlled by both the FixLJ-FixK2 and the NifA regulatory cascades. The fixRnifA operon is not only expressed under anaerobic but, to a lower level, also under aerobic conditions. One of two overlapping promoters and an upstream DNA region (UAS) are required for aerobic expression (Thöny et al. 1989, Barrios et al. 1995). A protein (UBP) binding to the UAS was postulated previously to act as an activator. UBP has now been purified and the corresponding gene has been cloned.
