| + | Matrix metalloproteinase 9 (MMP9) is a key regulator of the extracellular matrix (ECM), involved in the degradation of various ECM proteins. MMP9 is a member of a large family of proteases that are secreted as inactive zymogens. MMP9 plays a pathological role in a variety of inflammatory and oncology disorders and has long been considered an attractive therapeutic target. GS-5745 is a potent, highly selective humanized monoclonal antibody inhibitor of MMP9 that has shown promise in treating ulcerative colitis and gastric cancer. Here we describe the crystal structure of GS-5745:MMP9 complex and biochemical studies to elucidate the mechanism of GS-5745 inhibition of MMP9. GS-5745 binds MMP9 distal to the active site, near the junction between the prodomain and catalytic domain. GS-5745 inhibits MMP9 by two mechanisms: binding to active MMP9 allosterically inhibits MMP9 activity and binding to pro-MMP9 prevents MMP9 activation. | ||
