Methionine-oxidized horse heart cytochromes c. II. Conformation and heme configuration
The two products from the reaction of horse heart ferricytochrome c with Chloramine-T, the FIII and FII CT-cytochromes, contain modification of the methionines to methionine sulfoxides, but they areExpand
Thiosulfate‐ and hydrogen‐driven autotrophic denitrification by a microbial consortium enriched from groundwater of an oligotrophic limestone aquifer
Assessment of the nirS‐type denitrifier community in the groundwater confirmed the potential for sulfur‐ and hydrogen‐dependent chemolithoautotrophic denitrification as important metabolic feature widely spread among subsurface Denitrifiers at the Hainich Critical Zone Exploratory. Expand
Nitrogen Loss from Pristine Carbonate-Rock Aquifers of the Hainich Critical Zone Exploratory (Germany) Is Primarily Driven by Chemolithoautotrophic Anammox Processes
Results clearly demonstrate the relevance of anammox as a key process driving nitrogen loss from oligotrophic groundwater environments, which might further be enhanced through coupling with incomplete nitrification. Expand
State of heme in heme c systems: Cytochrome c and heme c models
Polarized resonance Raman spectra of horse heart ferricytochrome c as a function of pH in the range 1.0–12, in the presence of the extrinsic ligands imidazole, cyanide, and azide, and in 4 M urea,Expand
Growth promotion and inhibition induced by interactions of groundwater bacteria
An AlamarBlue® based high-throughput screening method that allowed for a fast and highly standardized evaluation of both growth-inhibiting and -promoting metabolites to enable further studies to elaborate and better understand complex inter-specific interactions and networks in aquatic communities as well as in other environments is developed.

Multiple, Compounding Disturbances in a Forest Ecosystem: Fire Increases Susceptibility of Soil Edaphic Properties, Bacterial Community Structure, and Function to Change with Extreme Precipitation
The intensity and frequency of ecosystem disturbances are shifting with climate change, and multiple disturbances in close succession have the potential to compound their independent effects andExpand
Determination of organoisothiocyanates alone and in mixtures with organoisocyanates or thioureas
An iodatometric method for the determination of organoisothiocyanates is described. The isothiocyanates are quantitatively converted with n-butyl-amine in dimethylformamide medium into theExpand
Nonaqueous redox determination of xanthates and organotrithiocarbonates with copper (II) nitrate in acetonitrile
Abstract N, N' -Diphenylbenzidine has been employed as an indicator in the titrations of xanthates and organotrithiocarbonates with copper(II) nitrate in acetonitrile medium. The color-changes fromExpand
Determination of primary and secondary amines alone and in mixtures with tertiary amines
An iodatometric method has been developed for the determination of primary and secondary amines that is based on their quantitative reaction with phenyl isothiocyanate in dimethylformamide to formExpand
Pro-opiomelanocortin Synthesized by Corticotrophs Bears Asparagine-linked Oligosaccharides Terminating with S 044 GalNAcf 11 , 4 GlcNAcf 11 , 2 Mana *
We have determined that 280% of the Asn-linked oligosaccharides on the glycosylated form of mouse adrenocorticotropin (15-kDa adrenocorticotropin (ACTH)) bear one or more branches terminatingExpand
