Crystal Structure of the Catalytic Domain of ADAMTS-5 in Complex with an Amino-2-indanol compound
Structural highlights
FunctionATS5_HUMAN Cleaves aggrecan, a cartilage proteoglycan, and may be involved in its turnover. May play an important role in the destruction of aggrecan in arthritic diseases. May play a role in proteolytic processing mostly during the peri-implantation period. Evolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMedSeveral inhibitors of a series of cis-1(S)2(R)-amino-2-indanol-based compounds were reported to be selective for the aggrecanases, ADAMTS-4 and -5 over other metalloproteases. To understand the nature of this selectivity for aggrecanases, the inhibitors, along with the broad spectrum metalloprotease inhibitor marimastat, were independently bound to the catalytic domain of ADAMTS-5, and the corresponding crystal structures were determined. By comparing the structures, it was determined that the specificity of the relative inhibitors for ADAMTS-5 was not driven by a specific interaction, such as zinc chelation, hydrogen bonding, or charge interactions, but rather by subtle and indirect factors, such as water bridging, ring rigidity, pocket size, and shape, as well as protein conformation flexibility. Structural and inhibition analysis reveals the mechanism of selectivity of a series of aggrecanase inhibitors.,Tortorella MD, Tomasselli AG, Mathis KJ, Schnute ME, Woodard SS, Munie G, Williams JM, Caspers N, Wittwer AJ, Malfait AM, Shieh HS J Biol Chem. 2009 Sep 4;284(36):24185-91.
