Institute for General Microbiology, University of Berne Altenbergrain 21, CH 3013 Bem, Switzerland
Received June 26, 1979.
The sequence of tRNA tyrosine from the fission yeast Schixosaccharomyces pombe is pCUCCUGAUm
GGUG
AGDDGGDDAUCACACor(
)CCGGCUG
A1 AACCGGUUGm7 GUm5 GCUAGT
CGm1 AUUCUGGCUCAGGAGACCAOH. This sequence differs in 30 nucleotides from the tRNA-Tyr sequence of the budding yeast Saccharomyces cerevisiae. It has a unique anticodon stem of only four GC base pairs. The normal fifth pair position of nucleotide 2844 is occupied by a CU and in 20% of the tRNA-Tyr moleculea it is
-U. This unusual feature and its implications are considered in the discussion.
