| 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. |
