  • Title: Mosquito mitochondrial transfer RNAs for valine, glycine and glutamate: RNA and gene sequences and vicinal genome organization.
    Author: Dubin DT, HsuChen CC, Tillotson LE.
    Journal: Curr Genet; 1986; 10(9):701-7. PubMed ID: 2452025.
    Abstract:
    We report the sequences of 3 transfer RNAs from mosquito (Aedes albopictus) mitochondria, those for valine (anticodon UAC), glutamic acid (anticodon UUC) and glycine (anticodon UCC), as well as sequences for the corresponding genes and for some neighboring mitochondrial genes. TRNAval is notable for its high level of psi, tRNAglu for its low level of G and C, and tRNAgly is notable in that it appears as two species widely separated in gel electrophoresis, differing only in modification status. TRNAglu is the first sequenced insect mitochondrial tRNA that would be expected to engage in U.R wobble (where U is a modified U in the first position of the anticodon, and R is G or A in the third position of codons), if the insect system followed the modified wobble rules proposed for mammalian and fungal mitochondria; and the sequence determined does fit the proposal. The gene for tRNAval follows immediately that for 12S ribosomal RNA. The gene for tRNAglu occurs in a cluster of 6 tRNA genes that is separated from the gene for tRNAgly by a short reading frame. Features of the DNA sequences are discussed with reference to Drosophila, and mammalian, mitochondrial genome organization.
