Rhizobia-legume symbiosis is the most well researched biological nitrogen fixation system. Coating legume seeds with rhizobia is now a recognized practical measure for improving the production of legume corp. However, the efficacy of some commercial rhizobia inoculants cannot be guaranteed in China due to the low rate of live rhizobia in these products. A greenhouse experiment was conducted to ...

We have investigated the physiochemical characteristics of trypsin-treated, molybdate-stabilized glucocorticoid-receptor complexes from rat liver in the presence of 10 mM sodium molybdate by high performance ion-exchange chromatography, high performance size-exclusion chromatography, and sedimentation analysis. Trypsin treatment was performed under conditions previously reported to degrade the ...

the complexation of sodium molybdate with para-sulfonatocalix [4] arene was studied in thetemperature range from 20 to 40 °c and ph = 5.8 by spectroscopic method in water solution. thestability constants of complexes were calculated by the multiwavelength analysis of spectral datausing squad program. the equilibrium constant, spectroscopic data, molar absorptivities andconcentrations of all spe...

Molybdenum is very toxic to agricultural animals. Mo-reducing bacterium can be used to immobilize soluble molybdenum to insoluble forms, reducing its toxicity in the process. In this work the isolation of a novel molybdate-reducing Gram positive bacterium tentatively identified as Bacillus sp. strain A.rzi from a metal-contaminated soil is reported. The cellular reduction of molybdate to molybd...

The aryl hydrocarbon receptor (AhR) is a cytosolic basic helix-loop-helix protein that associates with a chaperone complex that includes two molecules of heat shock protein 90 (HSP90). It has been hypothesized that after ligand binding, the AhR dissociates from its chaperone complex and translocates into the nucleus, where it heterodimerizes with its DNA binding partner, the AhR nuclear translo...

The structure of the type I tetraheme cytochrome c(3) from Desulfovibrio desulfuricans G20 was determined to 1.5 Angstrom by X-ray crystallography. In addition to the oxidized form, the structure of the molybdate-bound form of the protein was determined from oxidized crystals soaked in sodium molybdate. Only small structural shifts were obtained with metal binding, consistent with the remarkabl...
