Alignment of CtsR-binding sites identified upstream from ctsR, hsp18, clpX, grpE, clpP, groES, and clpL2 genes of O. oeni IOB 8413 (ATCC BAA-1163). Identical nucleotides are shaded. The numbers indicate positions relative to the transcriptional start site. GenBank accession numbers for database sequences are as follows: clpL2 (AJ890337), groES (AJ890340), grpE (AJ890339), ctsR (AJ890338), hsp18 (AJ250422), clpX (Y15953), and clpP (AJ606044).
