To define domains of tissue inhibitor of metalloproteinases (TIMP-1) that are important to its ability to inhibit fibroblast-type collagenase (FIB-CL), two different approaches were used: (i) competition with synthetic peptides modeled after the human TIMP-1 sequence and (ii) localization of epitopes of blocking antibodies. TIMP-1 consists of six loops, held in place by six disulfide bonds arranged in three knotlike structures.
