Disease relevance of RNF25

• In addition, a Microtox test showed that toxicity of the solution increased as a result of AO7 oxidation using this catalytic system [1].
• The water purification potential of this new class of compound was evaluated by studying the photodegradation of Acid Orange 7 (AO7) and E. coli [2].

High impact information on RNF25

• We found that both the RING finger and the C-terminal regions of AO7 were necessary for the transcriptional activation [3].
• TiO2/Cr(VI)/Acid Orange 7 (AO7), TiO2/Cr(VI)/Rhodamine B (RhB), TiO2/Ag+/AO7, and TiO2/Ag+/RhB were chosen as test systems [4].
• Acid Green 25 (AG25), Crystal Violet (CVI), Methylene Blue (MB), and Acid Orange 7 (AO7), representing paradigms of four types of commercial organic dyes, were therefore investigated in terms of their redox behavior [5].
• The adsorption of a model textile azo-dye, Acid Orange 7 (AO7), on the surface of titanium dioxide was extensively investigated in aqueous TiO(2) suspensions over wide ranges of AO7 concentrations (1 x 10(-4)-3 x 10(-3) M) and pH values (2-10) [6].
• A vertical-flow CW, planted with Phragmites sp. was fed with 127 mgl(-1) of acid orange 7 (AO7) at hydraulic loads of 28, 40, 53 and 108 l m(-2) day(-1) [7].

Biological context of RNF25

• At a HRT of 8h, a more extensive reductive biotransformation was observed for DR254 (82%) than for AO7 (56%) [8].
• The disappearance of AO7 followed pseudo first-order kinetics, whereas its mineralization could be described by zero-order kinetics [9].
• Orange II, C.I. Acid Orange 7 (AO7), is oxidatively decolorized via catalytic oxidation by iron(III) phthalocyanine-tetrasulfonic acid (Fe(III)-PcTS) as a biomimetic catalyst and KHSO(5) as an oxygen donor [1].
• The biosorption of Acid red 88 (AR88), Acid green 3 (AG3) and Acid orange 7 (AO7) by deactivated fresh water macro alga Azolla filiculoides was investigated in batch mode [10].

Associations of RNF25 with chemical compounds

• The photodestruction of Acid Orange 7 (AO7), an anionic acidic dye, was studied in the UV/H2O2 process [11].
• Complete loss of color, sulfanilic acid, and chemical oxygen demand (COD) indicate that AO7 is mineralized [12].
• During mineralization of AO7, strain ICX reduces the azo bond under aerobic conditions and consumes the resulting cleavage product 1-amino-2-naphthol [12].
• This study examined the photocatalytic degradation of three azo dyes, acid orange 7 (AO7), procion red MX-5B (MX-5B) and reactive black 5 (RB5) using a new type of nitrogen-doped TiO2 nanocrystals [13].
• The decolorization of C.I. Acid Orange 7 (AO7), an anionic monoazo dye of acid class, was investigated using UV radiation in the presence of H2O2 in a tubular continuous-flow photoreactor as a function of oxidant and dye concentrations, reactor length and volumetric flow rate [14].

Analytical, diagnostic and therapeutic context of RNF25

• Results obtained with the use of a variety of techniques, including potentiometric titrations, adsorption isotherms, adsorption edges, and microelectrophoresis, were used for the description of the "AO7 solution/TiO(2) surface" interface [6].
• The determination of the adsorption mode of TiO(2), which is supported by ex situ FTIR results, as well as of the adsorption constant, K(ads), allowed the description of the pH dependency of the AO7 adsorption over large pH and AO7 concentration ranges [6].
• A stable microbial biofilm community capable of completely mineralizing the azo dye acid orange 7 (AO7) was established in a laboratory scale rotating drum bioreactor (RDBR) using waste liquor from a sewage treatment plant [12].
• Two bacterial strains (ICX and SAD4i) originally isolated from the RDBR were able to mineralize, in co-culture, up to 90% of added AO7 [12].
• Although, HPLC chromatograms showed that 1-amino-2-naphthol, the other AO7 cleavage metabolite, was removed, aeration batch assays demonstrated that this could be due to auto-oxidation and not biological mineralization [8].
