| gabT | ycnG | + | 441571..442881 | COG0160E | gabT-BAC | |
| gabD | ycnH | + | 442950..444338 | COG1012C | gabD-BAC |
| Operon evidence: | lacZ gene fusion to gabT and gabTD; 5' primer extension analysis of the downstream glcU-gdh operon; Northern blotting (2.6 kb transcript) |
|---|---|
| Reference: | Belitsky BR & Sonenshein AL (2002), BSORF |
| Comments: | The lacZ fusions showed that an internal promoter (sigma factor unknown) exists between gabT and gabD. The Northern blotting results in BSORF only showed the gabTD transcript. |
