ENZYME: 3.4.24.27

Entry

EC 3.4.24.27                Enzyme

Name

thermolysin;
Bacillus thermoproteolyticus neutral proteinase;
thermoase;
thermoase Y10;
TLN

Class

Hydrolases;
Acting on peptide bonds (peptidases);
Metalloendopeptidases

Reaction(IUBMB)

Preferential cleavage: !Leu > !Phe

Comment

A thermostable extracellular metalloendopeptidase containing four calcium ions. Enzymes that may be species variants of thermolysin are reported from Micrococcus caseolyticus [4] and Aspergillus oryzae [5]. Type example of peptidase family M4. Closely related but distinct enzymes are aeromonolysin, pseudolysin, bacillolysin, aureolysin and mycolysin

History

EC 3.4.24.27 created 1972 as EC 3.4.24.4, part transferred 1992 to EC 3.4.24.27
