Entry
EC 3.4.24.65                Enzyme                                 

Name
macrophage elastase;
metalloelastase;
human macrophage metalloelastase (HME)
Class
Hydrolases;
Acting on peptide bonds (peptidases);
Metalloendopeptidases
BRITE hierarchy
Reaction(IUBMB)
Hydrolysis of soluble and insoluble elastin [1]. Specific cleavages are also produced at -Ala14!Leu- and -Tyr16!Leu- in the B chain of insulin [2]
Comment
This enzyme is synthesized as a proenzyme of 53 kDa that is converted to an active form of 22 kDa. cDNA sequences have been obtained for the mouse [3] and human [4] enzymes. In peptidase family M10 (interstitial collagenase family)
