Abstract
Besides its major role in protein synthesis, wheat germ arginyl-tRNAArg can serve as an amino acid donor in an enzymatic reaction to bovine serum albumin catalysed by the enzyme arginyl-tRNAArg: protein transferase. The nucleotide sequence of the tRNAArg involved in this reaction was determined to be: pG-A-C-U-C-C-G-U-m1G-m2G-C-C-C-A-A-D-Gm-G-A-X-A-A-G-G-C-m2(2) G-C-U-G-G-U-Cm-U-I-C-G-m2A-A-A-C-C-A-G-A-G-A-D-U-m5C-U-G-G-G-T-psi -C-G-m1 A-U-C-C-C-C-A-G-C-G-G-A-G-U-C-G-C-C-AOH. We suggest that the decapentanucleotide 5'-G-U-Pu-m2G-C-N-C-A-A-D-Gm-G-A-X-A-3', localized in the D-region, interacts specifically with the protein transferase.
