FIG. 1.
Map of the ykvU-stoA operon in the B. subtilis chromosome. Shown also are DNA segments cloned in plasmids used for disruption of stoA (pLLE39), for complementation analysis (pLLE83), and for deletion of ykvU-stoA (pLLE77). The hooked arrow and the loop indicate a σE-dependent promoter and a transcription terminator, respectively.
