How bacterial organelles assemble

Added: 22.06.2017 23:52 | 0 views | 0 comments

Scientists are providing the clearest view yet of an intact bacterial microcompartment, revealing at atomic-level resolution the structure and assembly of the organelle's protein shell. This work could benefit research in bioenergy and pathogenesis, and it could lead to new methods of bioengineering bacteria for beneficial purposes.

Assembly principles and structure of a 6.5-MDa bacterial microcompartment shell

Added: 22.06.2017 20:55 | 2 views | 0 comments


Many bacteria contain primitive organelles composed entirely of protein. These bacterial microcompartments share a common architecture of an enzymatic core encapsulated in a selectively permeable protein shell; prominent examples include the carboxysome for CO2 fixation and catabolic microcompartments found in many pathogenic microbes. The shell sequesters enzymatic reactions from the cytosol, analogous to the lipid-based membrane of eukaryotic organelles. Despite available structural information for single building blocks, the principles of shell assembly have remained elusive. We present the crystal structure of an intact shell from Haliangium ochraceum, revealing the basic principles of bacterial microcompartment shell construction. Given the conservation among shell proteins of all bacterial microcompartments, these principles apply to functionally diverse organelles and can inform the design and engineering of shells with new functionalities.

High fat diet reduces gut bacteria, Crohn's disease symptoms

Added: 22.06.2017 19:52 | 0 views | 0 comments

A high fat diet may lead to specific changes in gut bacteria that could fight harmful inflammation -- a major discovery for patients suffering from Crohn's disease, research indicates. Crohn's disease, a type of inflammatory bowel syndrome, causes debilitating intestinal swelling, cramping, and diarrhea. The disease affects half a million people in the United States, but its cause is yet unclear.

Simple method measures how long bacteria can wait out antibiotics

Added: 21.06.2017 23:59 | 1 views | 0 comments

A simple test that measures how long it takes to kill bacteria could help doctors treat strains that are on their way to becoming resistant to antibiotics. If implemented in hospitals' microbiology labs, the test could help guide treatment decisions, and could ultimately reduce the ever-growing risk of bacterial resistance.

Blocking yeast-bacteria interaction may prevent severe biofilms that cause childhood tooth decay

Added: 21.06.2017 18:03 | 0 views | 0 comments

In early childhood caries, a severe form of tooth decay that affects more than a third of toddlers in the US, yeast often partners with bacteria to form an intractable biofilm. New research reveals the mechanisms and suggests a way to block the interaction and reduce plaque.
