Nucleotide sequence of a spinach chloroplast valine tRNA

Nucleotide sequence of a spinach chloroplast valine tRNA

The nucleotide sequence of a spinach chloroplast valine tRNA (sp. chl.tRNAVal) has been determined. This tRNA shows essentially equal homology to prokaryotic valine tRNAs (58–65% homology) and to the mitochondrial valine tRNAs of lower eukaryotes (yeast and N. crassa, 61-62% homology). Sp. chl.tRNA...

Zusammenfassung:The nucleotide sequence of a spinach chloroplast valine tRNA (sp. chl.tRNAVal) has been determined. This tRNA shows essentially equal homology to prokaryotic valine tRNAs (58–65% homology) and to the mitochondrial valine tRNAs of lower eukaryotes (yeast and N. crassa, 61-62% homology). Sp. chl.tRNA a shows distinctly lower homology to mouse mitochondrial valine tRNA (53% homology) and to eukaryotic cytoplasmic valine tRNAs (47–53% homology).Sp. chl. tRNAVal, like all other chloroplast tRNAs sequenced, contains a methylated GG sequence in the dihydrouridine loop and lacks unusual structural features which have been found in several mitochondrial tRNAs.
