Novel Genes Encoding 2-Aminophenol 1,6-Dioxygenase fromPseudomonas Species AP-3 Growing on 2-Aminophenol and Catalytic Properties of the Purified Enzyme

Adsorption Isotherms 2-aminophenol and 4-aminophenol on Carbon Nonotube

Present research paper deals with the adsorption isotherms rate 2-amino phenol and 4-amino phenol on multi-wall carbon nanotube which performed by changing the amount of solution concentration in ppm unit. According to difference between two under studied substances are in substitution of NH2 in ortho and para position , more adsorption of 4-aminophenol on carbon nanotube demonstrate that para ...

Crystallization and preliminary crystallographic analysis of 2-aminophenol 1,6-dioxygenase complexed with substrate and with an inhibitor.

Dioxygen activation implemented by nonhaem Fe(II) enzymes containing the 2-His-1-carboxylate facial triad has been extensively studied in recent years. Extradiol dioxygenase is the archetypal member of this superfamily and catalyzes the oxygenolytic ring opening of catechol analogues. Here, the crystallization and preliminary X-ray analysis of 2-aminophenol 1,6-dioxygenase, an enzyme representi...

Electrocatalytic oxidation of formaldehyde on novel composite of nickel/triton-x100/poly(o-aminophenol-co-aniline)

Oxidation of formaldehyde (HCHO) is very important, owing to its use in fuel cells. Modification of electrodes surfaces is an excellent way to decrease the overpotentials as well as to increase the current density of the voltammetric response.pt as most efficient metal catalyst can easily be poisoned by product of oxidation and also it has high cost. In this work an efficient and low cost elect...

The enzymatic conjugation of m-aminophenol.

It has been demonstrated by many workers (l-5) that phenols may be conjugated with glucuronic acid or inorganic sulfate in vitro by liver slices and by cell-free preparations. By using a system developed in this laboratory, together with a modification of the analytical procedure described by Levvy and Storey (3), the synthesis of the conjugated sulfate, and possibly of the glucuronide, has bee...
