The ygaVP genes of Escherichia coli form a tributyltin-inducible operon.

ABSTRACT: A tributyltin (TBT) luxAB transcriptional fusion in Escherichia coli revealed that a TBT-activated promoter is located upstream of two cotranscribed orphan genes, ygaV and ygaP. We demonstrate that transcription from the promoter upstream of ygaVP is constitutive in a ygaVP mutant, suggesting that YgaV is an autoregulated, TBT-inducible repressor.
