Ca2+ | there are two adjacent calcium ions seemingly firmly bound inside the surface of the molecule by chelation to five acidic groups: Asp138, Glu177, Asp185, Glu190 and Asp191, two additional calcium binding sites are at exposed surface regions, one chelated by Asp57 and possibly also by Asp59 and the other chelated by Asp200 | Bacillus thermoproteolyticus | |
Zinc | the three zinc ligands are two histidines and glutamic acid | Bacillus thermoproteolyticus |
