生物活性: Imidazole is a planar 5-membered ring. Imidazole is a highly polar compound. Imidazole has been used extensively as a corrosion inhibitor. Imidazole is incorporated into many important biological molecules. The most pervasive is the amino acid histidine, which has an imidazole side-chain. Imidazole is useful as a buffer in the pH range of 6.2-7.8 One of the applications of imidazole is in the purification of His-tagged proteins in immobilised metal affinity chromatography(IMAC). Imidazole is used to elute tagged proteins bound to Ni ions attached to the surface of beads in the chromatography column. An excess of imidazole is passed through the column, which displaces the His-tag from nickel co-ordination, freeing the His-tagged proteins. Imidazole has become an important part of many pharmaceuticals. Synthetic imidazoles are present in many fungicides and antifungal, antiprotozoal, and antihypertensive medications. Imidazole is part of the theophylline molecule, found in tea leaves and coffee beans, which stimulates the central nervous system. It is present in the anticancer medication mercaptopurine, which combats leukemia by interfering with DNA activities.

生物活性: Carboxypeptidase B is a peptide exonuclease that can specifically degrade peptide chains. Carboxypeptidase B is progressively degraded from the C-terminal to release free amino acids. Carboxypeptidase B hydrolyzes only peptide bonds with basic amino acids (such as arginine and lysine) as C-terminal residues.

生物活性: Carboxypeptidase A (EC 3.4.2.1) is a zinc-containing metalloprotease, is often used in biochemical studies. Carboxypeptidase A catalyzes the hydrolysis of the peptide bonds that are adjacent to the C-terminal end of a polypeptide chain. Carboxypeptidase A is a prototypical enzyme for metalloproteases that plays important roles in biological systems.
