The primary structure of rabbit, calf and bovine liver tRNAPhe.

Highly purified tRNAPhe from rabbit liver, calf liver and bovine liver were completely digested with pancreatic ribonuclease and ribonuclease T1. The oligonucleotides were separated and identified. The tRNAPhe from rabbit liver and calf liver were partially cleaved with ribonuclease T1 or by action of lead acetate. We describe the analyses of the large fragments and the derivation of the primary structure of these mammalian tRNAsPhe.
