Neutral zinc metallopeptidases, zinc-binding region signature




Description

The majority of zinc-dependent metallopeptidases (with the notable exception of the carboxypeptidases) share a common pattern of primary structure [1,2,3] in the part of their sequence involved in the binding of zinc, and can be grouped together as a superfamily,known as the metzincins, on the basis of this sequence similarity. They can be classified into a number of distinct families [4,E1] which are listed below along with the proteases which are currently known to belong to these families.

 Family M1
 - Bacterial aminopeptidase N (EC 3.4.11.2) (gene pepN).
 - Mammalian aminopeptidase N (EC 3.4.11.2).

   hydrolysis of an  epoxide moiety of LTA-4 to form LTB-4;  it has been shown
   that it binds zinc and is capable of peptidase activity.

 Family M2
 - Angiotensin-converting enzyme (EC 3.4.15.1) (dipeptidyl carboxypeptidase I)
   (ACE) the enzyme  responsible  for hydrolyzing angiotensin I to angiotensin
   II. There  are  two  forms of ACE:  a testis-specific isozyme and a somatic
   isozyme which has two active centers.

   neurotransmitter release by proteolytic  cleavage of synaptic proteins such

   enzyme from Thermus aquaticus which is most active at high temperature.

   from various species of Aspergillus.

 Family M36
 - Extracellular elastinolytic metalloproteinases from Aspergillus.

From the tertiary structure of thermolysin, the position of the residues acting as zinc ligands and those involved in the catalytic activity are known. Two of the zinc ligands are histidines which are very close together in the sequence; C-terminal to the first histidine is a glutamic acid residue which acts as a nucleophile and promotes the attack of a water molecule on the carbonyl carbon of the substrate. A signature pattern which includes the two histidine and the glutamic acid residues is sufficient to detect this superfamily of proteins.
