Operon evidence: RNAse protection mapping of the 3' terminus of the ctaB transcript; genome analysis
Reference: Liu X & Taber HW (1998)
Comments: The RNAse protection mapping of the 3' end showed that ctaB transcription ends at the end of the stem-loop downstream of ctaB. A longer transcript was also detected, which may be due to glucose-mediated readthrough at the ctaB terminator.
