FIG. 2.

Proposed structure of the region of the B. subtilis chromosome that encompasses the ccpB gene. (A) The arrangement of genes surrounding the ccpB gene is depicted. The map shows the proposed gene and protein assignments, the direction of transcription (indicated by the open arrows), and the numbers of base pairs (in parentheses) in the intergenic regions. The solid bar labeled B indicates the position of the region shown in panel B. (B) The nucleotide sequence preceding the exoA gene. The sequence includes an imperfect palindrome that might serve as a Rho-independent terminator (indicated by the arrows) and two overlapping regions which show similarity with each other and the cre consensus sequence (13). See text for details.
