Peptidase_M3

Peptidase_M3
PFAM accession number:PF01432
Interpro abstract (IPR001567):

This group of metallopeptidases belong to MEROPS peptidase family M3 (clan MA(E)), subfamilies M3A and M3B. The protein fold of the peptidase domain for members of this family resembles that of thermolysin, the type example for clan MA.

The Thimet oligopeptidase family, is a large family of archaeal, bacterial and eukaryotic oligopeptidases that cleave medium sized peptides. The group contains:

GO process:proteolysis (GO:0006508)
GO function:metalloendopeptidase activity (GO:0004222)

This is a PFAM domain. For full annotation and more information, please see the PFAM entry Peptidase_M3
