RESUMO
We have previously shown that IS5 contains two genes encoded on opposite DNA strands within the same stretch of DNA. Here we present evidence that a third gene and its promoter are present on IS5. The newly discovered gene, ins5C , is contained within the longest gene of IS5, ins5A , but encoded by the complementary DNA strand. The three genes comprise a total of 519 codons present on the 1195-bp element. The arrangement of these genes represents a coding structure of unprecedented compactness.
