Sequences of halobacterial tRNAs and the paucity of U in the first position of their anticodons.
The sequence of three tRNAs from Halobacterium cutirubrum have been determined. The sequences of tRNAValGAC and tRNAValCAC differ by only one nucleotide which is in the 5' terminal anticodon position. These tRNAs as well as that of tRNAAlaCGC are compared to other known halobacterial tRNAs. An observed paucity (or absence) of U in the first anticodon position is unique to archaebacterial tRNAs and may be indicative of unusual decoding properties of these organisms.
