In its severe form, the disease affects the gums of 10–15% of adults, potentially leading to tissue destruction and tooth loss13. Its major causal agent is Porphyromonas gingivalis, a bacterium that is also implicated in cardiovascular diseases, respiratory diseases, diabetes, osteoporosis and pre...
The light-harvesting-reaction center complex (LH1-RC) from the purple phototrophic bacteriumThiorhodovibriostrain 970 exhibits an LH1 absorption maximum at 960 nm, the most red-shifted absorption for any bacteriochlorophyll (BChl)a-containing species. Here we present a cryo-EM structure of the ...
As was evident throughout the previous volume in this treatise, practically any method of studying natural bacterial communities upsets them while permitting only limited assessment of the respective qualities and quantitative contributions to total com munity activity of each type of bacterium present. ...

Although a given bacterial species has a basic, characteristic PG structure, the PG layer remains in a dynamic state throughout a bacterium's life, and PG structure is the result of complex biosynthetic, maturation, and degradation reactions, which will be described below. Structural analysis of ...
In Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis, there are eleven STPKs that play a central role in the physiology and pathogenesis, acting over hundreds of substrates that participate in all biological processes of the bacterium (Prisic and Husson, 2014; Wagner et al.,...
