Crystallization (Commentary)

Crystallization (Comment) Organism
density functional theory and polarized continuum model study. The optimized geometries show a large structural variability of the A-cluster depending on the oxidation state and the ligand attached to the proximal nickel atom. The calculated pKa values and redox potentials are in favor of the two-electron reduction mechanism coupled to a proton transfer Carboxydothermus hydrogenoformans

Metals/Ions

Metals/Ions Comment Organism Structure
Nickel enzyme contains two-center zerovalent nickel complexes. The proximal nickel atom Ni easily assumes planar, tetrahedral, and intermediate type coordination Carboxydothermus hydrogenoformans
