Fig. 4From: Four thiol-oxidoreductases involved in the formation of disulphide bonds in the Streptomyces lividans TK21 secretory proteinsInduction of the secretion stress response in the Sli-Dsbs deficient strains overproducing alpha-amylase. Quantitative RT-PCR analyses showed that the expression of the cssS and cssR increased in the Sli-Dsbs deficient strains overproducing alpha-amylase with respect to the wild type strain overproducing alpha-amylase. The values are the mean of at least three biological replicates. Bars show the standard errorBack to article page
