FIG 4.
β-Galactosidase activities of PspaS-lacZ inreporter strain B6633.MB1 after 60 min of induction with N-terminal entianin fragments. (A) Induction with entianin (3 to 15 nM) and the corresponding fragments entianin1–19 and entianin1–20. (B) Induction with S-entianin and the corresponding succinylated fragments S-entianin1–19 and S-entianin1–20. Error bars represent the standard deviation between results for samples from at least three separate cultures (n ≥ 3); measurements were carried out in duplicate.
