Laboratory of chemistry, Jichi Medical School, Minamikawachi-machi Tochigi-ken, 329-04, Japan
Received November 23, 1977.
A threonine tRNA was purified from Bacillus subtilis W168 by a combined use of column chromatographic systems. The nucleotide sequence was determined to be pG-C-C-G-G-U-G-U-A-G-C-U-C-A-A-U-D-G-G-D(U)-A-G-A-G-C-A-A-C-U-G-A-C-U-mo5U-G-U-t6A-A-
-C-A-G-U-A-G-m7G-U-U-G-G-G-G-G-T-
-C-A-A-G-U-C-C-U-C-U-U-G-C-C-G-G-C-A-C-C-AOH, where about 40% of D20 remained unmodified as U20. It consists of 76 nucleotides including a new minor nucleoside, 5-methoxyuridine (mo5U) which occupies the wobble position of anticodon.
