Yellow lupin cytoplasmic tRNAGlu is not a cofactor in chlorophyll biosynthesis.
Yellow lupin seeds (Lupinus luteus) cytoplasmic tRNAGlu was isolated and the primary structure was determined to be: (sequence in text) AGU CCCGGCGACGGAACCAOH. It is 76 nucleotides long and contains 8 modified nucleosides: 2 residues of pseudouridine, ribothymidine, 3 dihydrouridines, 5-methylcytosine and 1-methyladenosine. This tRNAGlu assayed in delta-aminolevulinic acid synthesis was shown to be inactive. Its structural features are discussed.
