Abstract

The major valine acceptor tRNA1Val from rabbit liver was purified and its nucleotide sequence determined by in vitro [32P] - labeling with T4 phage induced polynucleotide kinase and finger-printing techniques. Its primary structure was found to be identical with the major valine tRNA from mouse myeloma cells. According to the wobble hypothesis this tRNA, which exclusively has an IAC anticodon, should decode the valine codons GUU, GUC and GUA only. However, this tRNA recognizes all four valine codons with a surprising preference for GUG. It is unknown whether this is due to the lack of A37 modification next to the 3' end of the anticodon IAC. The nature of the inosine-guanosine interaction remains to be clarified.
