| ansR | + | 2456178..2456528 | transcriptional regulator (Xre family) | COG1396 | ansR-BAC | 
| Operon evidence: | Northern blotting; upstream and downstream genes are on the opposite strand | 
|---|---|
| Reference: | Sun D & Setlow P (1993), BSORF | 
| Comments: | Northern blotting results in BSORF suggest that ansR is transcribed in the opposite direction as part of the nudF-yqxK-ansAB and the nudF-yqxK-ansAB-yqkIJK transcripts. The terminator proposed by Sun & Setlow, near the ansR stop codon, is not recognized by mfold and lacks a T-stretch. |
