Zn2+ | a zinc-binding protease. The metal center in human IDE is chelated by His108, His112, and Glu189. The more external residues Tyr831, Glu111, Thr220, Gly221, Glu182, and Arg824 are also determined. Among these last residues, mainly Glu182, although not directly involved as metal ligand, plays a fundamental role in influencing metal recognition and binding by zinc proteins | Homo sapiens |

additional information | IDE shows catalytic activity toward two peptides of different length, simulating a portion of B chain of insulin, analysis by density functional theory method and the hybrid exchange-correlation functional B3LYP in gas phase and in the protein environment, modelling, reaction mechanism, overview. The proteolysis reaction is exothermic and proceeds quickly as the barrier in the rate-limiting step falls widely within the range of values expected for an enzymatic catalysis | Homo sapiens | ? | - |
