(A) Bacillithiol levels during YpdA overexpression. BSH and BSSB were measured in WT carrying empty vector (open) or vector with overexpression of YpdA (closed), under normal and stress conditions after 45 min exposure. Data are expressed as the mean and standard deviation (n=3). Significance was determined using Student t-test (* P ≤ 0.05).
(B) Redox ratio during YpdA overexpression. Redox ratio was calculated by dividing reduced amount of BSH by oxidized BSSB for WT strain carrying empty vector (open) or carrying overexpression of YpdA (closed). Data are expressed as the mean with standard deviation, significance was determined using Student t-test (** P ≤ 0.01).
