The gene for the prototype acute phase reactant, Creactive protein, has been isolated from two X phage libraries containing inserted human DNA fragments using synthetic oligonucleotide probes. Nucleotide sequence analysis indicates that after coding for a signal peptide of 18 amino acids and the first two amino acids of the mature protein, there is an intron of 278 base pairs followed by the nu...
متن کامل2-(4-Sulfamoylphenyl)hydrazin-1-ium chloride
The hydrazinium residue in the cation of the title salt, C(6)H(10)N(3)O(2)S(+)·Cl(-), is twisted out of the plane of the benzene ring to which it is attached [N-N-C-C torsion angle = 25.9 (2)°] and the amino group is almost perpendicular to the benzene ring [N-S-C-C torsion angle = 88.71 (16)°]. In the crystal, the cations are linked by N-H⋯O hydrogen bonds and π-π inter-actions [ring centroid ...
متن کامل4-(4-Methoxyphenyl)piperazin-1-ium chloride
In the title compound, C(11)H(17)N(2)O(+)·Cl(-), the dihedral angle between the benzene ring and the basal plane of piperazine ring is 39.20 (8)°. In the crystal, intermolecular N-H⋯Cl hydrogen bonds occur. There is also a C-H⋯π inter-action between the benzene rings.
متن کامل2-(4-Bromoanilino)-6-(4-chlorophenyl)-5-methoxycarbonyl-4-methyl-3,6-dihydropyrimidin-1-ium chloride
In the title molecular salt, C19H18BrClN3O2 (+)·Cl(-), the dihedral angles between the pyrimidine ring and the chlorobenzene and bromobenzene rings are 72.4 (2) and 45.5 (2)°, respectively. The dihedral angle between the chlorobenzene and bromobenzene rings is 27.5 (2)°. The conformation of the mol-ecule is stabilized by an intra-molecular C-H⋯O inter-action. In the crystal, the anion and catio...
متن کامل4-Carboxypyridazin-1-ium chloride
The structure of the title compound, C(5)H(5)N(2)O(2) (+)·Cl(-), is composed of chloride anions and 4-carboxy-pyridazin-1-ium cations. Chloride anions bridge the cations via O-H⋯Cl and N-H⋯Cl hydrogen bonds to form ribbons. The latter, linked by van der Waals forces with lengths in the range 3.254 (2)-3.497 (2) Å, form coplanar layers. Very weak inter-actions operate also between adjacent layer...
