CC   -!- FUNCTION: Arylacetonitrilase which is capable of hydrolyzing indole-3-
CC       acetonitrile (IAN) to the plant hormone indole-3-acetate (IAA), and
CC       allows the plant pathogenic bacterium to use IAN as a sole nitrogen
CC       source. Is also able to hydrolyze phenylpropionitrile (PPN), allowing
CC       the use of this compound as a sole nitrogen source. This enzyme may
CC       represent an additional mechanism for IAA biosynthesis or may be used
CC       to degrade and assimilate aldoximes and nitriles produced during host
CC       plant secondary metabolism. {ECO:0000269|PubMed:19849791}.

CC         Evidence={ECO:0000269|PubMed:19849791};
CC   -!- DISRUPTION PHENOTYPE: Cells lacking this gene are unable to grow in
CC       medium in which the sole nitrogen source is either indole-3-
CC       acetonitrile (IAN) or phenylpropionitrile (PPN). Their growth is also
CC       moderately reduced in medium with ammonia as the nitrogen source; one
CC       possible explanation for this phenotype is that the disruption of
CC       Psyr_0007 results in the accumulation of endogenous nitriles that can
CC       no longer be degraded and which inhibit bacterial growth.
CC       {ECO:0000269|PubMed:19849791}.
CC   -!- SIMILARITY: Belongs to the carbon-nitrogen hydrolase superfamily.
CC       Nitrilase family. {ECO:0000305}.
