| pheB | - | 2851383..2851826 | chorismate mutase | COG4492 | ||
| pheA | - | 2850509..2851366 | prephenate dehydratase | COG0077 | 
| Operon evidence: | S1 protection | 
|---|---|
| Reference: | Trach K & Hoch JA (1989), Sun D & Setlow P (1993) | 
| Comments: | S1 protection assay showed that pheB and pheA belong to the same operon, but did not fix the location of the terminator. Internal promoter in front of pheA. |
