Redetermination of 3-methylisoquinoline at 150 K
The structure of the title compound, C(19)H(9)O, has been redetermined at 150 K. The redetermination is of significantly higher precision than a previous room-temperature structure [Ribar et al. (1974 ▶). Cryst. Struct. Commun.3, 323-325]. The C-N bond lengths for this redetermination are much closer to those observed in comparable structures, and the orientation of the methyl group with respec...
متن کاملCrystal Structure of Nonaaquayttrium(III) Bromate at 100 K
The structure of the nonaaquayttrium (III) bromate, [Y(H2O)9](BrO3)3, at low temperature (100 K) has been studied by means of single-crystal X-ray diffraction. Crystallography shows a hexagonal unit cell, space group P63/mmc (No. 194) with Z = 2, a = b = 11.7104(11) Å, c = 6.6259(5) Å and V = 786.90(12) Å3 at 100 K. The hydra...

متن کامل3-Fluorobenzoic acid–4-acetylpyridine (1/1) at 100 K
In the title compound, C(7)H(5)FO(2)·C(7)H(7)NO, a moderate-strength hydrogen bond is formed between the carboxyl group of one mol-ecule and the pyridine N atom of the other. The benzoic acid mol-ecule is observed to be disordered over two positions with the second orientation only 4% occupied. This disorder is also reflected in the presence of diffuse scattering in the diffraction pattern.
متن کاملRates of unfolding, rather than refolding, determine thermal stabilities of thermophilic, mesophilic, and psychrotrophic 3-isopropylmalate dehydrogenases.
The relationship between the thermal stability of proteins and rates of unfolding and refolding is still an open issue. The data are very scarce, especially for proteins with complex structure. Here, time-dependent denaturation-renaturation experiments on Thermus thermophilus, Escherichia coli, and Vibrio sp. I5 3-isopropylmalate dehydrogenases (IPMDHs) of different heat stabilities are present...
