From: Global regulation of gene expression in response to cysteine availability in Clostridium perfringens
Alignment of the 4 cysteine specific T-boxes present in the C. perfringens genome. 4 genes with a T-box motif (AATTAGAGTGGAACC allowing one mismatch) were regulated in response to cysteine availability in transcriptome. We multialign a 200 bp region covering the T-box motif located upstream of these 4 genes. The conserved motifs characteristic of T-boxes (AGTA-box, F-box, AG-box, GNUG- box) are indicated. The cysteine specifier codon is boxed. Base-paired positions in the specifier hairpin (dotted arrow) are indicated by gray background. The bases involved in the formation of the antiterminator structure are underlined.
