Degradation of 2,4-dihydroxibenzoic acid by vacuum UV process in aqueous solution: kinetic, identification of intermediates and reaction pathway.

Kamal Azrague et al.

Journal of hazardous materials, 237-238, 71-78 (2012-09-15)

2,4-Dihydroxybenzoic acid (2,4-DHBA) is found frequently as a pollutant in natural waters and represents a threat to water quality because it is a precursor to the formation of quinones which are highly toxic. The degradation of 2,4-DHBA using the vacuum

Crystal structures of wild-type p-hydroxybenzoate hydroxylase complexed with 4-aminobenzoate,2,4-dihydroxybenzoate, and 2-hydroxy-4-aminobenzoate and of the Tyr222Ala mutant complexed with 2-hydroxy-4-aminobenzoate. Evidence for a proton channel and a new binding mode of the flavin ring.

H A Schreuder et al.

Biochemistry, 33(33), 10161-10170 (1994-08-23)

The crystal structures of wild-type p-hydroxybenzoate hydroxylase from Pseudomonas fluorescens, complexed with the substrate analogues 4-aminobenzoate, 2,4-dihydroxybenzoate, and 2-hydroxy-4-aminobenzoate have been determined at 2.3-, 2.5-, and 2.8-A resolution, respectively. In addition, the crystal structure of a Tyr222Ala mutant, complexed with

Degradation of 2,4-dihydroxybenzoate by Pseudomonas sp. BN9.

A Stolz et al.

FEMS microbiology letters, 108(2), 219-224 (1993-04-01)

The aerobic degradation of 2,4-dihydroxybenzoate by Pseudomonas sp. BN9 was studied. Intact cells of Pseudomonas sp. BN9 grown with 2,4-dihydroxybenzoate oxidized 2,4-dihydroxybenzoate but not salicylate. Cell-free extracts of Pseudomonas sp. BN9 converted 2,4-dihydroxybenzoate after the addition of NAD(P)H.
