interactions which can be done when more structural information is available, but they do provide order of magnitude estimates of interaction strengths. Evidently, considerable rearrangement of charge driven by reduction significantly raises the effective dielectric. It seems likely that centres S-2 and FR-2 are apparently low-potential clusters merely because they are the middle clusters in th...
متن کاملTitanium(IV) imido complexes of imine imidazol-2-imine ligands.
Free imine imidazol-2-imine ligands with two different substitution patterns have been isolated for the first time and they were found to exist as an equilibrium mixture of geometric and mesomeric isomers. The relative ratios of these isomers are dependent on both the nature of the substituents and of the solvent. The synthesis of the titanium(IV) alkyl and arylimido complexes of these ligands ...

متن کاملVirus-Encoded Ribonucleotide Reductases
Ribonucleotide reductases [EC 1.17.4.] are a group of enzymes which critically contribute to the biosynthesis of deoxyribonucleotides (dNTPs), the monomeric precursors of DNA polymerization. By a radical reaction mechanism, they catalyze the reduction of the ribonucleotides, ADP, GDP, CDP, and UDP, mostly at the diphosphate level, to their deoxy conterparts dADP, dGDP, dCDP, and dUDP, respectiv...

dehydrogenases. The same effects obtained when e N A D + is bound to binary complexes confirm the transfer of the coenzyme to a more hydrophobic environment, but also indicate that the coenzyme is bound to ODH in an open conformation, as found in other dehydrogenases. The high degree of conformational rigidity of bound coenzyme were deduced on the one hand from the negligible temperature coeffi...
