Guanidinium 4-aminobenzoate
In the title compound, CH(6)N(3) (+)·C(7)H(6)NO(2) (-), the cation and anion lie on crystallographic mirror planes. The 4-amino-benzoate anion is almost in a planar conformation with a maximum deviation of 0.024 (2) Å for the N atom. The bond length in the deprotonated carboxyl group is inter-mediate between those of normal single and double Csp(2)=O bonds, indicating delocalization of the char...
متن کامل4-Chloroanilinium (4-chlorophenyl)guanidinium dichloride hemihydrate
In the title hydrated molecular salt, C(6)H(7)ClN(+)·C(7)H(9)ClN(3) (+)·2Cl(-)·0.5H(2)O, the water O atom lies on a crystallographic twofold axis. In the crystal, inter-molecular N-H⋯Cl and O-H⋯Cl hydrogen bonds form layers perpendicular to the ac plane in which both the water mol-ecule and the chloride anion are involved in connecting the layers into a three-dimensional structure.
متن کاملUnimpaired de novo synthesis of 4-aminobenzoate in a mutant of Aerobacter aerogenes requiring 4-aminobenzoate for growth; structure of compond A.
The mutant strain A erobacter aerogenes 62-1 AC, pab, accumulates a labile substance, desig nated Compound A which supports the growth of other pabmutants. Previous studies seemed to indicate that Compound A might be an intermediate in the conversion of chorismate to 4-aminobenzoate (Altendorf, Bacher, and Lingens, Z. Naturforsch. 24 b, 1602 [1969]). The present experi ments show that Compoun...
متن کاملGuanidinium chlorochromate
In the title compound, guanidinium chloridotrioxidochrom-ate(VI), (CH(6)N(3))[CrClO(3)], both the cation and anion are generated by crystallographic mirror symmetry, with one O and one N atom and the Cr, Cl and C atoms lying on the mirror plane. The bond lengths in the guanidinium cation are inter-mediate between normal C-N and C=N bond lengths, indicating significant delocalization in this spe...
متن کاملNutritional requirement for 4-aminobenzoate caused by mutation of dihydropteroate synthetase.
Aerobacter aerogenes mutant 62-1 AC requires high concentrations of 4-aminobenzoate for growth. The mutant accumulates N-glucosyl-4-aminobenzoate and has an intact 4-aminobenzoate synthetase (Bacher, Gilch, Rappold, and Lingens, Z. Naturforsch. 28 c, 614-617 [1973]). On the other hand the ability of the mutant to synthesize dihydropteroate is markedly reduced. The dihydropteroate synthetase lev...
