title: Identification of a modified nucleoside located in the first position of the anticodon of Torulopsis utilis tRNAPro as 5-carbamoylmethyluridine.
abstract: An unknown nucleoside in the first position of the anticodon of Torulopsis utilis tRNAPro has been isolated. The UV, 1H NMR and secondary ion mass spectra indicated that this nucleoside is a uridine derivative, 5-carbamoylmethyluridine. The structure was completely established by comparison of the instrumental analysis results and chromatographic behavior of the isolated nucleoside with those of a synthetic sample.
