Calcium binding to thermitase. Crystallographic studies of thermitase at 0, 5, and 100 mM calcium.

The three-dimensional crystal structure of thermitase complexed with eglin-c in the presence of 100 mM calcium has been determined and refined at 2.0-A resolution to a R-factor of 16.8%. This crystal structure is compared with previously determined structures of thermitase at 0 and 5 mM calcium concentration. In the presence of 100 mM calcium all three… CONTINUE READING
