Streptomyces bacteria have a linear chromosome and a complex life cycle, including development of multi-genomic hyphae that differentiate into mono-genomic exospores. Here, Szafran et al. show that the chromosome of Streptomyces venezuelae undergoes

Bacterial chromosome topology is controlled by topoisomerases and nucleoid-associated proteins (NAPs). While topoisomerases regulate DNA supercoiling, NAPs introduce bends or coat DNA upon its binding, affecting DNA loop formation. Streptomyces, hyph

The coordination of chromosome segregation with cell growth is fundamental to the proliferation of any organism. In most unicellular bacteria, chromosome segregation is strictly coordinated with cell division and involves ParA that moves the ParB nuc

Bacteria of the genus Streptomyces have a linear chromosome, with a core region and two ‘arms’. During their complex life cycle, these bacteria develop multi-genomic hyphae that differentiate into chains of exospores that carry a single copy of t

AdpA is a key regulator of morphological differentiation in Streptomyces . In contrast to Streptomyces griseus , relatively little is known about AdpA protein functions in Streptomyces coelicolor . Here, we report for the first time the translation a

The dynamic, mitosis-like segregation of bacterial chromosomes and plasmids often involves proteins of the ParA (ATPase) and ParB (DNA-binding protein) families. The conversion of multigenomic aerial hyphae of the mycelial organism Streptomyces coeli

An improved, simplified method for the purification of recombinant, tagged DnaA proteins is described. The presented protocol allowed us to purify soluble DnaA proteins from two different bacterial species: Helicobacter pylori and Streptomyces coelic

Bacterial chromosome replication is mediated by single initiator protein, DnaA, that interacts specifically with multiple DnaA boxes located within the origin (oriC). We compared the architecture of the DnaA–origin complexes of evolutionarily dista
