The simplest amino acid, glycine (NH2CH2COOH), has long been searched for in the interstellar medium but has not been unambiguously detected so far. At the same time, more and more complex molecules have been newly found toward the prolific Galactic center source Sagittarius B2. Since the search for glycine has turned out to be extremely difficult, we aimed at detecting a chemically related species (possibly a direct precursor), amino acetonitrile (NH_2_CH_2_CN). With the IRAM 30m telescope we carried out a complete line survey of the hot core regions Sgr B2(N) and (M) in the 3mm range, plus partial surveys at 2 and 1.3mm. We analyzed our 30m line survey in the LTE approximation and modeled the emission of all known molecules simultaneously. We identified spectral features at the frequencies predicted for amino acetonitrile lines having intensities compatible with a unique rotation temperature. We also used the Very Large Array to look for cold, extended emission from amino acetonitrile.2008A&A...482..179Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/482/179CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/482/179https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/482/179http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/482/179https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/482/179https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/482/179http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/482/179GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalRadiodefaultJ/A+A/482/179/mapsList if FITS filesrecnoRecord number assigned by the VizieR team.
