A previously unrecognized group of metalloenzymes enables human gut microbes to metabolize dietary molecules and neurotransmitters and likely mediates interactions and metabolism among environmental microorganisms.
A structural and functional analysis of the electron transfer complex between a sulfite oxidase and its redox protein partner reveals an elegant compromise between the requirements for fast and efficient electron transfer and reaction specificity.
Bioinformatics and experimental approaches identify families of membrane proteins requiring the co-ordinated action of the Sec pathway and Tat pathways for their integration and define features of the polypeptides that mediate interaction with these pathways.
The genome of Thermovibrio ammonificans encodes ancestral pathways (e.g., hydrogen oxidation) and more recently acquired ones (e.g., nitrate reduction) and a hybrid pathway for CO2 fixation.
