Degradation of insulin, glucagon and other polypeptides. No action on proteins
Glu111 serves as a base to activate a catalytic water molecule within the active site of the enzyme, mediating peptide hydrolysis, mutation of this residue to glutamine renders IDE inactive, the catalytic water that is coordinated by a zinc ion also interacts with a glutamate residue, which serves as the general acid/base catalyst, catalytic mechanism
Degradation of insulin, glucagon and other polypeptides. No action on proteins
ability of substrates to properly anchor their N-terminus to the exosite of IDE and undergo a conformational switch upon binding to the catalytic chamber of IDE can also contribute to the selective degradation of structurally related growth factors. The high dipole moment of substrates complements the charge distribution of the IDE catalytic chamber for the substrate selectivity

the catalytic mechanisms for the hydrolysis of the three different peptide bonds (Lys28-Gly29, Phe19-Phe20, and His14-Gln15) of amyloid beta peptide is determined: For all these peptides, the nature of the substrate is found to influence the structure of the active enzyme-substrate complex.

investigation of activity of IDE regarding cleavage site's preferentiality upon modification of environmental factors by atmospheric pressure/laser desorption ionization-mass spectrometry. The first insulin fragments produced by IDE are mainly [A (1-13) + B (1-9)], [A (1-14) + B (1-9)] and [A (1-14) + B (1-10)]. A second set of insulin fragments involving the C-terminal residues of the insulin A chain [A (14-21) and A (15-21)] and the fragments B (17-24) and B (17-25) are then produced, confirming a delayed action of IDE on these cleavage sites.

somatostatin in addition to being a substrate, is also able to bind to two additional exosites, which play different roles according to the size of the substrate and its binding mode to the catalytic cleft of the enzyme. One exosite, which displays high affinity for somatostatin, regulates only the interaction of insulin-degrading-enzyme with larger substrates (such as insulin and beta-amyloid1-40) in a differing fashion according to their various modes of binding to the enzyme. A second exosite, which is involved in the regulation of enzymatic processing by the enzyme of all substrates investigated (including a 10-25 amino acid long amyloid-like peptide, bradykinin and somatostatin itself), probably acts through the alteration of an open-closed equilibrium

IDE is involved in the clearance of many bioactive peptide substrates, including insulin and amyloid beta, peptides vital to the development of diabetes and Alzheimer's disease, respectively. IDE can also rapidly degrade hormones that are held together by intramolecular disulfide bond(s) without their reduction. Furthermore, IDE exhibits a remarkable ability to preferentially degrade structurally similar peptides such as the selective degradation of insulin-like growth factor-II and transforming growth factor-alpha, TGF-alpha, over IGF-I and epidermal growth factor, respectively. IDE cleaves its substrates at multiple sites in a biased stochastic manner

i.e. BDM44768, catalytic site inhibitor, designed by kinetic target-guided synthesis. Selectively inhibits insulin-degrading enzyme. Crystallographic and small angle X-ray scattering analyses show that it locks insulin-degrading enzyme in a closed conformation. Acute treatment of mice with BDM44768 increases insulin signalling and impairs glucose tolerance in an insulin-degrading enzyme-dependent manner. The results casts doubt on the general usefulness of the inhibition of insulin-degrading enzyme catalytic activity to treat diabetes

By virtue of its potency, stability, specificity for insulin-degrading enzyme, low cost of synthesis, and demonstrated ability to potentiate insulin-induced processes involved in wound healing and skin health, the inhibitor holds significant therapeutic and cosmetic potential for topical applications

the oxidative burst of BV-2 microglial cells leads to oxidation of secreted IDE at Cys residues, e.g. Cys819, Cys110, Cys257, and Cys178, leading to the reduced activity after 4 h versus amyloid beta degradation, increases IDE oligomerization, and decreases IDE thermostability. Within the first 4 h of incubation at 37°C, the control and H2O2-treated enzyme does not lose any relative activity. The inhibitory response of IDE is substrate-dependent, biphasic for amyloid beta degradation but monophasic for a shorter bradykinin-mimetic substrate, mutational analysis, overview. Only Cys819 modification plays a prominent role in the change of enzyme properties

alpha-synuclein
a peptide with the C-terminal 44 residues of alpha-synuclein increases insulin-degrading enzyme proteolysis to the same degree as full-length alpha-synuclein. A peptide containing the first 97 residues of alpha-synuclein does not improve insulin-degrading enzyme activity. Because the alpha-synuclein C-terminus is acidic, the interaction appears to involve electrostatic attraction with basic exosite of insulin-degrading enzyme

Somatostatin
-
somatostatin binding to IDE brings about a concentration-dependent structural change of the secondary and tertiary structure of the enzyme, revealing two possible binding sites. The higher affinity binding site disappears upon inactivation of IDE by ethylenediaminetetraacetic acid, which chelates the catalytic Zn2+ ion
Somatostatin
enhances the proteolytic processing of a synthetic beta-amyloid-peptide. In addition to being a substrate, somatostatin is also able to bind to two additional exosites, which play different roles according to the size of the substrate and its binding mode to the catalytic cleft of the enzyme. One exosite, which displays high affinity for somatostatin, regulates only the interaction of insulin-degrading-enzyme with larger substrates (such as insulin and beta-amyloid1-40) in a differing fashion according to their various modes of binding to the enzyme. A second exosite, which is involved in the regulation of enzymatic processing by the enzyme of all substrates investigated (including a 10-25 amino acid long amyloid-like peptide, bradykinin and somatostatin itself), probably acts through the alteration of an open-closed equilibrium
