5-(isopentenylaminomethyl)uridine and 2-thio-5-(isopentenylaminomethyl)uridine were identified in tRNA of Thermodesulfobacterium commune. Their identities were determined by mass spectrometry and confirmed by chemical synthesis. Data were presented at the tRNA meeting in Banz, Germany (1985) by P.F. Crain, D.R. Phillips, T. Hashizume and F. Widdel. Since then, beside the Banz-meeting abstract, no paper was published about these modified nucleosides.
