Nucleotlde sequence of a spinach chloroplast proline tRNA

Abstract
The nucleotide sequence of a spinach chloroplast proline tRNA (sp. chl. tRNApro) has been determined. This tRNA. shows more overall homology to phage T4 proline tRNA (61% homology) than to eukaryotic proline tRNAs (53% homology) or mitochondrial proline tRNAs (36–49% homology). Sp. chl. tRNApro, like all other chloroplast tRNAs sequenced, contains a methylated GG sequence in the dihyrouridine loop and lacks unusual structural features which have been found in many mitochondrial tRNAs.
