Propyl 4-hydroxybenzoate
There are two mol-ecules in the asymmetric unit of the title compound, C(10)H(12)O(3). In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds into chains running along [010]. Adjacent chains are joined together by weak π-π inter-actions between benzene rings [centroid-centroid distance = 4.040 (2) Å].
متن کاملOxygen 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 کاملPropyl 2-(4-methylbenzenesulfonamido)benzoate
In the title compound, C(17)H(19)NO(4)S, the terminal ethyl group is disordered over two sets of sites, with refined site occupancies of 0.536 (7) and 0.464 (7). The dihedral angle between the two aromatic rings is 81.92 (12)°. The mol-ecular conformation is stabilized by intra-molecular N-H⋯O and C-H⋯O hydrogen bonds, which generate S(6) motifs. In the crystal, mol-ecules are linked by C-H⋯O h...
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 کاملThe 4-hydroxybenzoate/4-aminophenazone chromogenic system used in the enzymic determination of serum cholesterol.
A single reagent, containing cholesterol oxidase, cholesterol esterase, peroxidase, 4-hydroxybenzoate, and 4-aminophenazone, is used in determining serum cholesterol. Analysis time is 15 min, and the standard curve is linear to 6.0 g/liter. Analytical recovery of cholesterol was 100.1 +/- 0.4%. Within-run precision (CV) was less than or equal to 1.4 1.4%, between-run less than or equal to 4.8%....
