The crystal structure of the C-terminal domain of the salmonella enterica pduo protein: An old fold with a new heme-binding mode [PDF]

, 2016
The two-domain protein PduO, involved in 1,2-propanediol utilization in the pathogenic Gram-negative bacterium Salmonella enterica is an ATP:Cob(I)alamin adenosyltransferase, but this is a function of the N-terminal domain alone.

The roles of B vitamins in phytoplankton nutrition: new perspectives and prospects [PDF]

, 2017
B vitamins play essential roles in central metabolism. These organic water-soluble molecules act as, or as part of, coenzymes within the cell. Unlike land plants, many eukaryotic algae are auxotrophic for certain B vitamins.

Methanogenesis from tetramethylammonium and choline in Methanococcoides methylutens Q3c requires a nonpyrrolysine monomethylamine methyltransferase homolog

Frontiers in Microbiology
Methanogenesis is a key biological process contributing to both global climate change and renewable energy via methane. Methylotrophic methanogenesis is an important, but often underappreciated, component of this process.

BluB/CobT2 fusion enzyme activity reveals mechanisms responsible for production of active form of vitamin B 12 by Propionibacterium freudenreichii [PDF]

, 2015
Background Propionibacterium freudenreichii is a food grade bacterium that has gained attention as a producer of appreciable amounts of cobalamin, a cobamide with activity of vitamin B 12 .

Correlated production and consumption of chloromethane in the Arabidopsis thaliana phyllosphere [PDF]

, 2017
Chloromethane (CH3Cl) is a toxic gas mainly produced naturally, in particular by plants, and its emissions contribute to ozone destruction in the stratosphere. Conversely, CH3Cl can be degraded and used as the sole carbon and energy source by specialised

Methane metabolism in the archaeal phylum Bathyarchaeota revealed by genome-centric metagenomics [PDF]

, 2015
Methanogenic and methanotrophic archaea play important roles in the global flux of methane. Culture-independent approaches are providing deeper insight into the diversity and evolution of methane-metabolizing microorganisms, but, until now, no compelling

Molecular Evolution of Aminoacyl tRNA Synthetase Proteins in the Early History of Life [PDF]

, 2011
Aminoacyl-tRNA synthetases (aaRS) consist of several families of functionally conserved proteins essential for translation and protein synthesis. Like nearly all components of the translation machinery, most aaRS families are universally distributed ...

Coexistence of two distinct Sulfurospirillum populations respiring tetrachloroethene - genomic and kinetic considerations [PDF]

, 2018
Two anaerobic bacterial consortia, each harboring a distinct Sulfurospirillum population, were derived from a 10 year old consortium, SL2, previously characterized for the stepwise dechlorination of tetrachloroethene (PCE) to cis-dichloroethene (cis-DCE)

Computer Modelling and Simulations of Enzymes and their Mechanisms

, 2006
Although the tremendous catalytic power of enzymes is widely recognized, their exact mechanisms of action are still a source of debate. In order to elucidate the origin of their power, it is necessary to look at individual residues and atoms, and ...
