摘要
The structure and the magnetic and electrochemical properties of the active center of purple acid phosphatases are modeled by a complex that mimics the terminal coordination of the tyrosine residue and was prepared with a new heptadentate phenola‐to ligand system. The instability of the reduced FeIIFeII state of the enzyme may be attributed to the terminal ligand, since the phenolato ligand in the model is a destabilizing factor.
