Fig. 5.
Zn2+ distances from directly interacting atoms when AZM is bound to the protein (top four panels, marked as “holo”) and when AZM is away from the protein (bottom four panels, marked as “apo”). The X-ray structure of AZM-hCAII-Zn2+ (holo) was taken from Ref. [12] and the same of hCAII-Zn2+ (apo) from Ref. [47].
