Computational Insights into ADAMTS4, ADAMTS5 andMMP13 Inhibitor Selectivity

The results obtained by means of Molecular Dynamicssimulations and Multiway Explorative Data Analysison ADAMTS4, ADAMTS5 and MMP13 complexed with Marimastatand two cis-1(S)2(R)-amino-2-indanol ligands suggestthat determinant characteristics for ligand binding andselectivity among the three enzymes are to be found in thedifferent protein conformation flexibility. Moreover, the role of the TS-domain in the inhibitor binding to ADAMTS enzymeshas been investigated for the first time in this work.The results obtained suggest that the influence of the TSdomainon the S1’ loop fluctuations of ADAMTS4 andADAMTS5 could be exploited for the design of therapeuticsfor chronic osteoarthritis diseases.
