. "The first transposable element to be isolated from Streptomyces fradiae, Tn4556, was completely sequenced; the total of 6625 bp have an overall G + C composition of 68%. Computer-aided analysis of this sequence reveals the location of nine open reading frames (ORFs). Several of these ORFs, numbers 1, 2, and 7, contain ribosome-binding sites (RBS) near their putative translation-initiation sites, which share identity with the consensus RBS sequences of Escherichia coli and Bacillus subtilis. ORF1 potentially encodes an 892-amino acid (aa) protein and this deduced aa sequence shares 61% identity with that of the transposase encoded by the tnpA gene of Tn3. Three other ORFs, 2, 3 and 5, potentially encode proteins which are similar in size to the resolvase protein encoded by the Tn3 gene tnpR; however, none of the protein products deduced from these ORF share extensive aa sequence identity with other resolvase proteins." . . .
