The genomes of phages—viruses that infect bacteria—are largely composed of "dark matter": genes that encode proteins whose functions remain unknown. Less than four years ago, a team led by Prof. Rotem ...
New insights into how bacteria control DNA synthesis open the door to next generation antimicrobials
Ribonucleotide reductases (RNR) are indispensable enzymes that convert ribonucleotides to deoxyribonucleotides (dNTPs), the precursors to make up DNA. Because DNA synthesis is fundamental to cell ...
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 ...
Researchers from Durham University, Jagiellonian University (Poland) and the John Innes Centre have achieved a breakthrough in understanding DNA gyrase, a vital bacterial enzyme and key antibiotic ...
Bacteria are constantly moving with the help of motility organs called flagella or pili to colonize new niches. Also, bacteria can exchange information, like "speaking to each other," and thus acquire ...
A recent study utilizing cryo-EM advances our understanding of how bacterial immune systems function and reveals new aspects ...
In the microscopic world of bacteria, gene transfer is a powerful mechanism that can alter cellular function, drive antibiotic resistance and even shape entire ecosystems. Now an interdisciplinary ...
PHILADELPHIA — Deep in the mangrove swamps of the Caribbean lives a giant bacterium with a surprise trick for organizing its DNA. Thiovulum imperiosus wraps its genetic material in membranous fingers, ...
