CC   -!- FUNCTION: Hydrolyzes most efficiently N-acetyl derivatives of aromatic
CC       amino acids but is also active on other amino acids. L-stereospecific.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=an N-acyl-L-amino acid + H2O = a carboxylate + an L-alpha-
CC         amino acid; Xref=Rhea:RHEA:15565, ChEBI:CHEBI:15377,
CC         ChEBI:CHEBI:29067, ChEBI:CHEBI:59869, ChEBI:CHEBI:59874; EC=3.5.1.14;
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=an N-acetyl-L-cysteine-S-conjugate + H2O = acetate + an S-
CC         substituted L-cysteine; Xref=Rhea:RHEA:36855, ChEBI:CHEBI:15377,
CC         ChEBI:CHEBI:30089, ChEBI:CHEBI:58717, ChEBI:CHEBI:58718; EC=3.5.1.14;
CC   -!- COFACTOR:
CC       Name=Co(2+); Xref=ChEBI:CHEBI:48828;
CC   -!- SUBUNIT: Homotetramer.
CC   -!- SIMILARITY: Belongs to the peptidase M20 family. {ECO:0000305}.
