Mutational analysis of the Myxococcus xanthus Omicron4499 promoter region reveals shared and unique properties in comparison with other C-signal-dependent promoters.

Abstract excerpt

The bacterium Myxococcus xanthus undergoes multicellular development during times of nutritional stress and uses extracellular signals to coordinate cell behavior. C-signal affects gene expression late in development, including that of Omega4499, an operon identified by insertion of Tn5 lac into the M. xanthus chromosome. The Omega4499 promoter region has several sequences in common with those found previously to...
