CC   -!- FUNCTION: Catalyzes the hydration of cyanide to formamide. Degradation
CC       of cyanide may be important for plant pathogenic fungi in infection of
CC       cyanogenic plants (By similarity) (PubMed:26521240). Can also transform
CC       some nitriles like 2-cyanopyridine and fumaronitrile and has a minor
CC       activity with 4-cyanophenyl acetonitrile (4-CPA) (PubMed:26521240).
CC       {ECO:0000255|HAMAP-Rule:MF_03224, ECO:0000269|PubMed:26521240}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=formamide = H2O + hydrogen cyanide; Xref=Rhea:RHEA:21720,
CC         ChEBI:CHEBI:15377, ChEBI:CHEBI:16397, ChEBI:CHEBI:18407; EC=4.2.1.66;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_03224,
CC         ECO:0000269|PubMed:26521240};
CC   -!- SUBUNIT: Oligomer of dimers, forming left-handed helical fibers.
CC       {ECO:0000255|HAMAP-Rule:MF_03224}.
CC   -!- INDUCTION: By cyanide. {ECO:0000255|HAMAP-Rule:MF_03224}.
CC   -!- SIMILARITY: Belongs to the carbon-nitrogen hydrolase superfamily.
CC       Nitrilase family. {ECO:0000255|HAMAP-Rule:MF_03224}.
