Swapping a single amino acid in a simple bacterial protein changes its structure and function, revealing the effects of complex gene evolution, finds a new study. The study -- conducted using E. coli ...

Textbook images show peptidoglycan as straight and ordered. The biopolymer peptidoglycan that makes up bacterial cell walls was always assumed to be highly ordered. Textbook images like the one below ...

Bacteria are constantly moving with the help of motility organs called flagella or pili to colonize new niches. Also, ...

MIT chemists have discovered the structure of a protein that can pump toxic molecules out of bacterial cells. Proteins similar to this one, which is found in E. coli, are believed to help bacteria ...

Bacterial fragments called peptidoglycans may influence daily sleep patterns and also affect the brain health cycle strongly.

New research into antimicrobial peptides, small chains of amino acids able to damage bacterial cells, shows why some peptides are more effective at doing that and also why some cells are more ...

Researchers at the University of Toronto have discovered that bacteria can drive stem cell regeneration to repair the ...

Swapping a single amino acid in a simple bacterial protein changes its structure and function, revealing the effects of complex gene evolution, finds a new study published in the journal eLife. The ...
