[Nucleotide sequence in tRNA Leu 2 from cow mammary gland]

The primary structure of the tRNA2Leu from a lactating cow mammary gland was established T1 and pancreatic ribonuclease digestion were determined by an ultramicrospectrophotometric method using the equipment for microcolumn chromatography. tRNA2Leu is composed of 85 nucleotide residues, including 15 modified nucleotides. The anticodon region of tRNA2Leu is respresented by the sequence CAG. The primary structures of tRNA2Leu from the cow mammary gland and leucine tRNAs from E. coli and yeast were compared.
