▪ Abstract Most prokaryotic signal-transduction systems and a few eukaryotic pathways use
phosphotransfer schemes involving two conserved components, a histidine protein kinase …

The phosphoenolpyruvate (PEP): carbohydrate phosphotransferase system (PTS) is found
only in bacteria, where it catalyzes the transport and phosphorylation of numerous …

A multiprotein complex that specifically recognizes cellular origins of DNA replication has
been identified and purified from the yeast Saccharomyces cerevisiae. We observe a strong …

High levels of the intracellular signalling molecule cyclic diguanylate (c‐di‐GMP) supress
motility and activate exopolysaccharide (EPS) production in a variety of bacterial species. In …

Nitrogen metabolism in prokaryotes involves the coordinated expression of a large number
of enzymes concerned with both utilization of extracellular nitrogen sources and intracellular …

This review presents a comparison between the complex genetic regulatory networks that
control nitrogen fixation in three representative rhizobial species, Rhizobium meliloti …

We present a comprehensive overview of the hierarchical network of intracellular processes
revolving around central nitrogen metabolism in Escherichia coli. The hierarchy intertwines …

Members of the diverse superfamily of AAA+ proteins are molecular machines responsible
for a wide range of essential cellular processes. In this review we summarise structural and …

Bacterial enhancer binding proteins (bEBPs) are transcriptional activators that assemble as
hexameric rings in their active forms and utilize ATP hydrolysis to remodel the conformation …

The interaction of bacteria with host cell surfaces causing virulence is effected by surface
adhesins named type IV pili. Pili is formed in Pseudomonas aeruginosa by proteolytic …
