The degradation of p-toluenesulfonate (TSA) by Comamonas testosteroni T-2 is initiated by a transport system (TsaST) and enzymes (TsaMBCD) encoded on the tsa transposon, Tntsa, on the TSA plasmid (pTSA). Tntsa comprises an insert of 15 kb between two IS1071 elements. The left-hand 6 kb and the right-hand 6 kb are nearly mir- ror images. The regulator of the tsaMBCD1 genes (right- hand side) is the centrally located LysR-type TsaR, which is encoded upstream of tsaMBCD1 on the reverse strand. The other centrally located genes are tsaS and tsaT, en- coded downstream of tsaR and on the same strand as both tsaR and tsaMBCD2. The latter four genes are not ex- pressed....
