title: Genetic analysis of the tdcABC operon of Escherichia coli K-12.
abstract: The biodegradative threonine dehydratase (tdc) operon was mapped at 68 min on the Escherichia coli K-12 chromosome. The order of markers in the clockwise direction was dnaG uxaA tdc argG. A tdc deletion was isolated and mapped to this region of the chromosome. By using a tdcB-lacZ fusion the clockwise direction of transcription of tdc was determined.
