CC   -!- FUNCTION: Presumably involved in the processing and regular
CC       turnover of intracellular proteins. Catalyzes the removal of
CC       unsubstituted N-terminal amino acids from various peptides.
CC       Required for plasmid ColE1 site-specific recombination but not in
CC       its aminopeptidase activity. Could act as a structural component
CC       of the putative nucleoprotein complex in which the Xer
CC       recombination reaction takes place.
CC   -!- CATALYTIC ACTIVITY: Release of an N-terminal amino acid, Xaa-|-
CC       Yaa-, in which Xaa is preferably Leu, but may be other amino acids
CC       including Pro although not Arg or Lys, and Yaa may be Pro. Amino
CC       acid amides and methyl esters are also readily hydrolyzed, but
CC       rates on arylamides are exceedingly low.
CC   -!- COFACTOR: Binds 2 manganese ions per subunit (By similarity).
CC   -!- ENZYME REGULATION: Inhibited by zinc and EDTA.
CC   -!- SUBUNIT: Homohexamer.
CC   -!- SIMILARITY: Belongs to the peptidase M17 family.
CC   -!- CAUTION: The ligation for manganese is based on the ligation for
CC       zinc, an inhibitor, in the crystallographic structure reported in
CC       PubMed:10449417. The ligation for manganese in the active form of
CC       the enzyme may differ.
