The interaction of the amyloid-beta peptide (Abeta) with thermolysin (TLN) was investigated by X-ray crystallography. Structural models of the complexes of TLN with several Abeta fragments show that, despite the numerous possible cleavage sites of the Abeta sequence, the C-terminal product of Ala30-Ile31 cleavage does not dissociate, thus inhibiting the enzyme. The high similarity between the TLN structural motif and neprilysin (NEP), the most extensively studied peptidase associated with Abeta clearance, suggests that NEP should be more efficient against Abeta polymorphs where Ala30-Ile31 is inaccessible, which is in agreement with studies in living mice that point to the limited role of NEP in degrading soluble Abeta and its higher ability to degrade insoluble and/or oligomeric Abeta forms, producing only the Abeta10-37 intermediate. | |||
