| Comments: | Internal promoter in front of resD, leading to a 2.5 kb transcript. Azevedo found a 7.0 kb transcript that started upstream of ypuL (in front of resA), as well as a shorter 0.7 kb transcript corresponding to ypuL only. The transcripts detected by Azevedo and Sun both had a length of 7 kb, which is 1 kb longer than needed for a resABCDE operon. In addition, Azevedo found that a probe for ypuL hybridizes to the 7 kb transcript, indicating that the transcript corresponds to ypuL-resABCDE. Such a transcript agrees well with the length of 7 kb measured by Northern blotting. However, Sun's primer extension experiment showed a single promoter just in front of resA. |
