comparison of the refined three-dimensional structure Thermoactinomyces vulgaris

Metals/Ions

Metals/Ions Comment Organism Structure
Ca2+ three calcium binding sites, two of these are tight binding sites, and removal of calcium causes unfolding and autolysis to occur. The third calcium is more weakly bound, its removal reduces the activity of the enzyme by 10%, the reduction being reversible Thermoactinomyces vulgaris
