FIG 1.

Scheme of the 9,029-bp DNA segment derived from sample SRX560289. Purple, indispensable genes for integration of mobile genetic elements. Yellow, intI (integrase/recombinase), tnpA (transposase), and the integron-associated recombination site (attI). Red, resistance genes (qacEΔ1, biocide resistance; sulI, sulfonamide resistance; the mphR(A)/mphA/mrx gene cluster, erythromycin resistance; and chrA, chromate resistance), except dfrB4 (dihydrofolate reductase, TMP resistance), which is blue. Orange, recombination binding site (attC). Dashed lines, 7-be sequences. Green, DNA sequences sharing similarity with known genes: GNAT/sulI3 (acetyltransferase/sulfonamide resistance) and padR (transcriptional regulator). Gray, the 62- and 4-bp sequence differences between DNA contigs.
