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.
已确定了来自深红嗜盐菌的三种tRNA的序列。tRNAValGAC和tRNAValCAC的序列仅在5'末端反密码子位置有一个核苷酸不同。将这些tRNA以及tRNAAlaCGC的序列与其他已知的嗜盐菌tRNA进行了比较。在第一个反密码子位置观察到的U的缺乏（或不存在）是古细菌tRNA所特有的，可能表明这些生物体具有不同寻常的解码特性。
