Figure 6

Expression of the reporter α-amylase gene from the iron-regulated desA promoter versus the non-regulated saf promoter. Experimental conditions were as in Fig. 5. ○, ●, pUL99DA; ▼, ▽, pULVD10. Closed symbols control cultures in LS medium; open symbols cultures induced by addition of the iron-chelator 2,2'-dipyridyl at time 0 (vertical arrows). Results are given as volumetric enzyme levels (panel A) or as specific enzyme production (panel B). The inclined arrows indicate the time of addition (0 h) of the 2,2'-dipyridyl inducer
