Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Ligands: CA, HAE, M4S, ZN Gene: HME, MMP12 (HUMAN) Activity: Macrophage elastase, with EC number 3.4.24.65 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function [MMP12_HUMAN] May be involved in tissue injury and remodeling. Has significant elastolytic activity. Can accept large and small amino acids at the P1' site, but has a preference for leucine. Aromatic or hydrophobic residues are preferred at the P1 site, with small hydrophobic residues (preferably alanine) occupying P3. Evolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMed For several drug leads obtained by tethering weak binding ligands, the dissociation constant is smaller than the product of those of the individual fragments by a factor named the linking coefficient, E. This favorable contribution is attributed to the entropic gain that is realized when two weak binding ligands are tethered. Here we show a case study where the linking coefficient is strikingly small (E = 2.1 x 10(-3) M(-1)) and its totally entropic nature is demonstrated.
