This experiment was to determine genome wide qualitative and quantitative differences in transcription starts under conditions of availability of iron or vanadium or molybdenum which act as co-factors for different nitrogenase isoenzymes. In response to availability of the co-factors transcription i...
Sterols are ubiquitous membrane constituents that persist to a large extent in the environment due to their water insolubility and chemical inertness. Recently, an oxygenase-independent sterol degradation pathway was discovered in a cholesterol-grown denitrifying bacterium Sterolibacterium (S.) deni...
ABSTRACT; Molybdenum (Mo) is an essential micronutrient for plants, serving as a cofactor for enzymes involved in nitrate assimilation, sulfite detoxification, abscisic acid biosynthesis and purine degradation. Here we show that natural variation in shoot Mo content across 92 Arabidopsis thaliana a...
Hydrogenotrophic methanogenic Archaea are defined by a H2 requirement for growth. Despite this requirement, many hydrogenotrophs are also capable of growth with formate as an electron donor for methanogenesis. Hydrogenotrophs respond to H2 starvation both phenotypically and at the level of gene expr...
