In Buchnera, however, the hypothesized loss of promoters suggests a general genomic decay influencing transcriptional regulation; this is supported by the observation that SD sequences are also degenerate, and by the finding that some of the most frequently used codons in the genome do not have corresponding tRNAs because they have been deleted throughout Buchnera 's evolution.
When E. coli Bl21(DE3), a strain that did not express additional rare tRNAs, was transformed with the cloned T. acidophilum ATPase A subunit, no additional protein bands were observed in extracts of induced cells (not shown).
Human mitochondrial DNA is much smaller, encoding 37 gene products (13 proteins, 2 rRNAs and 22 tRNAs) over 16,569 base pairs [ 3].
Since rare tRNAs generally correspond to rare codons [ 27], we checked whether a bias in codon usage was correlated with readthrough efficiency.
Although the region is not bracketed by IS elements or tRNAs that are characteristic of pathogenicity islands (PAIs), it bears features that are similar to the putative PAI identified in the B. anthracis plasmid pXO1 [ 20 ] . Bacterial sequences with similarity to the B. anthracis cap genes are present in sequence databases.
