description

The nucleotide sequence of a new tRNA(Leu)(anticodon U*AA) from Saccharomyces cerevisiae which could recognize exclusively the UUA codon has been determined. Its primary structure is: pGGAGGGUUGm2GCac4CGAGDGmGDCDAAGGCm2(2)GGCAGACmUU*AAm1GA++ + psi CUGUUGGACGGUUGUCCGm5CGCGAGT psi CGm1A(orA)ACCUCGCAUCCUUCACCA. This tRNA has a large extraloop and contains 15 modified nucleotides. So far it is the third isoacceptor tRNA for leucine in yeast. It has 61% homology with tRNA(Leu)(anticodon m5CAA) and 63% homology with tRNA(Leu)(anticodon UAG), the two other known yeast tRNAs(Leu).
