Received May 3, 1984. Revised October 5, 1984. Accepted October 5, 1984.
We have sequenced a 1.6 kbp region of the mosquito (Aedes albopictus) mitochondrial genome containing the large ribosomal subunit ("LSU") RNA gene, and have located the ends of the gene by 3 protection analylsis and by comparison with RNA sequences. The gene is preceded by a tRNAval gene and followed by genes for
(rather than
as in mammalian URF1. mitochondria) and an extended reading frame homologous to mammalian URF1 . It is approximately 1335 residues long and is very low (17;) in G+C. The 5' half is even lower in G+C (94), and shows little apparent homology to other LSU RNA classes. The 5' half is relatively rich (26;) in G+C and has many stretches of homology to prokaryotic and mammalian mitochondrial LSU RNA.
