RcsB is a highly conserved transcription regulator of the Rcs phosphorelay system, a
complex two-component signal transduction system (N. Majdalani and S. Gottesman, Annu …

The single-component RcoM transcription factor couples an N-terminally bound heme
cofactor with a C-terminal “LytTR” DNA-binding domain. Here the RcoM Bx-1 protein from …

ABSTRACT Ω4514 is the site of a Tn 5 lac insertion in the Myxococcus xanthus genome that
fuses lacZ expression to a developmentally regulated promoter. DNA upstream of the …

A vital point in gene regulation is control at the level of transcription initiation. Recent
research has established that this regulation can involve sophisticated networks of …

Using interaction trap technology, we identified a putative extracytoplasmic-function (ECF)
sigma factor (RpoE1) in Myxococcus xanthus, a bacterium which has a complex life cycle …

The cAMP receptor proteins (CRPs) play a critical role in bacterial environmental adaptation
by regulating global gene expression levels via cAMP binding. Here, we report the structure …

Eukaryotic cells utilize complex signaling systems to detect their environments, responding
and adapting as new conditions arise during evolution. The basidiomycete fungus …

M. xanthus cells possess two independent motility systems: the adventurous (A) system and
the social (S) system. S-motility depends on the extension and retraction of Type-4-pili …

cAMP Receptor Protein (CRP)/Fumarate Nitrate Reductase Regulator (FNR) family proteins
are ubiquitous regulators of cell stress in eubacteria. These proteins are commonly …

The marine picocyanobacterium Prochlorococcus contributes significantly to global primary
production, and its abundance and diversity is shaped in part by viral infection. Here, we …
