Characterization of the fMet initiator tRNA gene of Bartonella bacilliformis
Abstract
A ribosomal RNA operon was cloned from the agent of human Oroya fever, Bartonella bacilliformis. The 3' end of the operon contains a 77-nucleotide (nt) N-formylmethionine (fMet) initiator tRNA-encoding gene with 100% sequence identity to the fMet tRNA-encoding gene of Rhodobacter sphaeroides. The 3' region downstream from the gene has an 8-nt inverted repeat and 28 contiguous direct repeats of the heptamer 5'-TTCTCTA. To date, B. bacilliformis and R. sphaeroides are the only known eubacteria which have an fMet tRNA-encoding gene within the 3' end of their rRNA operons.
