1.14.11.17 additional information development of a colorimetric assay method, based on the measurement of sulfite using Ellman's reagent, i.e. 2.5 mM 5,5'-dithiobis(2-nitrobenzoic acid), for determination of taurine in commercially available beverages and some biological samples, overview 723940 1.14.11.17 additional information metal-to-ligand charge-transfer transition involving the 2-oxoglutarate ligand with a six-coordinate metal center. Taurine does not coordinate the Fe(II) ion, but binds in its close vicinity, leading to loss of the coordinating water molecule. This change of the six-coordinate to five-coordinate Fe(II) center causes a small perturbation of the absorption spectrum -, 724974 1.14.11.17 additional information structure-activity analysis, modeling and simulations, overview. Modeling of TauD-(Fe-NO) complex and spectral analysis 725787 1.14.11.17 physiological function cysteine metabolism 697475 1.14.11.17 physiological function important in antibiotic biosynthesis, oxygen sensing, DNA repair, biodegradation of anthropogenic compounds 701264 1.14.11.17 physiological function nonheme iron enzyme, activation of C-H bonds 697518 1.14.11.17 physiological function the enzyme catalyzes the hydroxylation of taurine eventually leading to sulfite production in Escherichia coli -, 765089 1.14.11.17 physiological function the enzyme is responsible for the microbial catabolism of taurine initiated by hydroxylation of C1 -, 764167 1.14.11.17 physiological function the enzyme metabolizes taurine as a sulfur source for sulfur-starved cells. TauD activates taurine via hydrogen atom transfer to an Fe(IV)=O intermediate -, 765270
