Figure 5

Iron regulation of expression of the reporter α-amylase gene coupled to the desA promoter in a multicopy transformant (pUL99DA) (panel A) and a low-copy number transformant (pUL99DA) (panel B) expressed as volumetric enzyme activity (panels A and B) or as specific activity (panel C). ○, ●, pUL99DA; ▼, ▽, pUL42DA. Closed symbols, control cultures in LS medium; open symbols, cultures induced with the iron-complexing agent 2,2'-dypirydyl added at time 0 (inclined arrows).
