1-Piperonylpiperazinium 4-chlorobenzoate
In the title salt {systematic name: 1-[(1,3-benzodioxol-5-yl)meth-yl]piperazin-1-ium 4-chloro-benzoate}, C12H17N2O2 (+)·C7H4ClO2 (-), the piperazine ring adopts a slightly disordered chair conformation. The dioxole ring is in a flattened envelope conformation with the methyl-ene C atom forming the flap. The relative orientation of the piperonyl ring system and the piperazine rings is reflected ...
متن کامل1-Piperonylpiperazinium 4-nitrobenzoate monohydrate
IN THE TITLE HYDRATED SALT [SYSTEMATIC NAME: 1-(1,3-benzodioxol-5-ylmeth-yl)piperazin-1-ium 4-nitro-benzoate monohydrate], C12H17N2O2 (+)·C7H4NO4 (-)·H2O, the piperazinium ring of the cation adopts a slightly distorted chair conformation. The piperonyl and piperazine rings are rotated with respect to each other with an N-C-C-C torsion angle of 45.6 (2)°. In the anion, the nitro group is almost ...

IN THE CATION OF THE TITLE SALT [SYSTEMATIC NAME: 4-(2H-1,3-benzodioxol-5-ylmeth-yl)piperazin-1-ium 2,4,6-tri-nitro-phen-o-late], C12H17N2O2 (+)·C6H2N3O7 (-), the piperazine ring adopts a slightly disordered chair conformation. The piperonyl ring system and the piperazine ring are twisted with respect to each other with an N-C-C-C torsion angle of 40.7 (2)°. In the anion, the dihedral angles be...
متن کاملRational redesign of the 4-chlorobenzoate binding site of 4-chlorobenzoate: coenzyme a ligase for expanded substrate range.
Environmental aromatic acids are transformed to chemical energy in bacteria that possess the requisite secondary pathways. Some of these pathways rely on the activation of the aromatic acid by coenzyme A (CoA) thioesterification catalyzed by an aromatic acid: CoA ligase. Adaptation of such pathways to the bioremediation of man-made pollutants such as polychlorinated biphenyl (PCB) and dichlorod...
متن کاملEnergy-dependent uptake of 4-chlorobenzoate in the coryneform bacterium NTB-1.
The uptake of 4-chlorobenzoate (4-CBA) in intact cells of the coryneform bacterium NTB-1 was investigated. Uptake and metabolism of 4-CBA were observed in cells grown in 4-CBA but not in glucose-grown cells. Under aerobic conditions, uptake of 4-CBA occurred with a high apparent affinity (apparent Kt, 1.7 microM) and a maximal velocity (Vmax) of 5.1 nmol min-1 mg of protein-1. At pH values belo...
