The tmCBP calcium binding site. Close-up view of the molecular interactions of tmCBP with an endogenously bound calcium ion (green sphere). Water molecules are shown as red spheres and amino acids involved in hydrogen bonding are represented as ball and stick models. Direct metal hydrogen bonds are represented as black-dashed lines whereas the remainder of the hydrogen bonding network is red. The LR5 crystal structure was used for this analysis.
