- *****************************************************
-
- Tissue inhibitors of metalloproteinases (TIMP) are a family of proteins [1,2,
- 3] that can form complexes with extracellular matrix metalloproteinases (such
- as collagenases) and irreversibly inactivate them. TIMP's are proteins of
- about 200 amino acid residues, 12 of which are cysteines involved in disulfide
- bonds [4]. The basic structure of such a type of inhibitor is shown in the
- following schematic representation:

-
- 'C': conserved cysteine involved in a disulfide bond.
- '*': position of the pattern.
-
- As a signature pattern for TIMP's, we chose the N-terminal extremity of these
- proteins, which includes three conserved cysteines.
-
- -Consensus pattern: C-x-C-x-P-x-H-P-Q-x-A-F-C
- [The three C's are involved in disulfide bonds]
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
