Inside every cell, thousands of molecular signals collide, overlap, and compensate, obscuring the true drivers of gene expression. Scientists have now developed a way to silence that cellular noise, ...

Heme binding to a bacterial transcription factor is critical for hydrogen sulfide (H 2 S) signaling, report researchers from Japan. Heme binding promotes the reaction of H 2 S with the transcription ...

Gene expression is linked to RNA transcription, which cannot happen without RNA polymerase. However, this is where the similarities between prokaryote and eukaryote expression end. Central to the ...

Researchers have revealed how bacteria precisely control the genes that trigger cell division. The study shows that the MraZ protein, which normally forms a donut-shaped structure, must bend and ...

Tuberculosis bacteria. Computer artwork of Mycobacterium tuberculosis bacteria, the Gram- positive rod-shaped bacteria which cause the disease tuberculosis. Life is governed by tiers of gene ...

A newly discovered promoter element "start" points to a shared regulatory syntax for controlling transcription initiation in bacteria, archaea, and eukaryotes. DNA is often described as the language ...

Inside every cell, thousands of molecular signals collide, overlap, and compensate, obscuring the true drivers of gene expression. Scientists have now developed a way to silence that cellular noise, ...

Cholera remains a major global public health challenge, with an estimated 1.3 to 4 million cases and tens of thousands of deaths reported worldwide each year. Caused by the bacterium Vibrio cholerae, ...

Researchers at Umeå University have identified a key molecular player that helps bacteria survive the hostile environment inside the body. Their study reveals how the protein RfaH acts as a protective ...
