CC   -!- FUNCTION: Catalyzes the hydrolysis of short-chain aliphatic amides to
CC       their corresponding organic acids with release of ammonia.
CC       {ECO:0000255|HAMAP-Rule:MF_01242}.
CC   -!- FUNCTION: Also exhibits in vitro acyl transferase activity,
CC       transferring the acyl moiety of short-chain amides to hydroxylamine to
CC       form hydroxamates. {ECO:0000255|HAMAP-Rule:MF_01242}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a monocarboxylic acid amide + H2O = a monocarboxylate +
CC         NH4(+); Xref=Rhea:RHEA:12020, ChEBI:CHEBI:15377, ChEBI:CHEBI:28938,
CC         ChEBI:CHEBI:35757, ChEBI:CHEBI:83628; EC=3.5.1.4;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01242};
CC   -!- SIMILARITY: Belongs to the carbon-nitrogen hydrolase superfamily.
CC       Aliphatic amidase family. {ECO:0000255|HAMAP-Rule:MF_01242}.
