Oxygen reaction of 4-hydroxybenzoate monooxygenase.
Among monooxygenases the flavin containing enzymes were the first being purified and crystallized since they consist of only one single protein in contrast to the multienzyme structure of the metal containing monooxygenases. Flavin plays a dual role in these enzymes acting as electron acceptor and oxygen activating site simultaneously. Kinetic measurements by NAKAMURA et al.1 on the 4-hydroxybe...
متن کاملHbaR, a 4-hydroxybenzoate sensor and FNR-CRP superfamily member, regulates anaerobic 4-hydroxybenzoate degradation by Rhodopseudomonas palustris.
Under anaerobic conditions, structurally diverse aromatic compounds are catabolized by bacteria to form benzoyl-coenzyme A (benzoyl-CoA), the starting compound for a central reductive pathway for aromatic ring degradation. The structural genes required for the conversion of 4-hydroxybenzoate (4-HBA) to benzoyl-CoA by Rhodopseudomonas palustris have been identified. Here we describe a regulatory...
متن کامل4-Hydroxyanilinium perchlorate dihydrate
In the crystal structure of the title compound, C(6)H(8)NO(+)·ClO(4) (-)·2H(2)O, inter-molecular N-H⋯O and O-H⋯O hydrogen bonds occur. The protonated amine cations and the perchlorate anions are linked through the water mol-ecules, and the hy-droxy groups of the cations and the anions are linked through the water mol-ecules. The cations are connected to the perchlorate anions via inter-molecula...
متن کاملTetrabutylammonium 4-hydroxybenzoate dihydrate
In the title compound, (n-C(4)H(9))(4)N(+)·C(7)H(5)O(3) (-)·2H(2)O, the carboxyl-ate group is twisted slightly out of the plane of the attached benzene ring, the two C-C-C-O torsion angles being -8.9 (2) and -10.7 (2)°. The anion inter-acts with two water mol-ecules through several O-H⋯O hydrogen bonds, forming wide ribbons along the a axis constructed from two anion-water chains. These ribbons...
متن کامل(E)-N′-(4-Ethoxybenzylidene)-4-hydroxybenzohydrazide dihydrate
The benzohydrazide mol-ecule of the title compound, C(16)H(16)N(2)O(3)·2H(2)O, exists in a trans conformation with respect to the C=N double bond. The central O=C-NH-N=C plane [r.m.s. deviation of 0.0165 (1) Å for the five non-H atoms] makes dihedral angles of 6.04 (8) and 2.38 (8)°, respectively, with the hy-droxy- and eth-oxy-substituted benzene rings. The dihedral angle between these benzene...
