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

G-quadruplex DNA structure is considered to be a very attractive target for antitumor drug design due to its unique role in maintaining telomerase activities. Therefore, discovering ligands with high stability of G-quadruplex structure is of great interest. In this paper

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
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. A partially

The spectra of radicals formed upon the addition of .OH radicals to the 3 position of substrates for p-hydroxybenzoate hydroxylase (4-hydroxybenzoic acid, 2,4-dihydroxybenzoic acid, and 4-aminobenzoic acid) have been determined using pulse radiolysis combined with the results from high performance
