FIG. 2.

The gab operon. The extents of the deletions and the insertion sites for SR1, SR2, SR4, and CP6 are indicated above the genes. The line below the genes indicates the proposed transcript. There is uncertainty concerning the start codons of three genes. The genes and coordinates (from the sequence with GenBank accession no. AE000351) of the first nucleotide of the start codons are as follows: ygaF, 1639 (GTG) or 1705 (ATG); gabT, 4452 or 4458 (both ATG); gabC/ygaE, 7379 or 7397 (both ATG). There are three repetitive extragenic palindromic elements between gabD and gabP.
