FIG. 6.

Alignment of upstream regions of chitinase genes and the genes for chitin-binding proteins. The experimentally determined transcriptional start sites are wavy underlined. The predicted −35 and −10 sequences for the RNA polymerase binding sites are double and single underlined, respectively. The sequences corresponding to the 12-bp direct repeat of the S. plicatus chi63 gene (5) are given in capitals; those identical with the direct repeat of the chi63 gene are shown in white on a black background. The strains have been abbreviated as follows: (c), S. coelicolor A3(2); (p), S. plicatus; (l), S. lividans; (o), S. olivaceoviridis.
