Comments: | Transcripts starting about 1.0 kb upstream of the indicated promoter were also detected. These may correspond to a ysgA-pheST transcript. Based on homology, transcriptional readthrough is expected to occur at the stem-loop upstream of pheS if uncharged phenylalanyl tRNA binds to the T-box motif in the nascent mRNA transcript. The tRNA anticodon binds to the UUC codon in the sequence GCCUUCACC in the pheS leader mRNA. |
