title: Primary structure of bovine liver tRNATrp.
abstract: Purified tRNATrp from bovine liver, accepting 1700 pmol tryptophan per A260nm unit, was completely digested with pancreatic ribonuclease and T1 ribonuclease. The sequences of the resulting oligonucleotides were determined and the primary structure of the tRNA was deduced. These analyses showed numerous incomplete post-transcriptional modifications, and several positions heterogenously occupied by two different nucleotides, which lead us to think that in bovine liver there exist a mixture of several tRNATrp.
