FIG. 3.

DNA of pRE1 that encodes phthalate and protocatechuate catabolism. This is a restriction map of a 26,274-bp segment divided into two parts. Below the restriction map are boxes indicating the locations of genes (described in Table 3). Below these are DNA fragments that have been cloned or subcloned (Table 1). Names of the plasmids carrying these fragments are indicated at the left. Arrows indicate possible promoters, while the small black box indicates a resolvase binding (res) site.
