Fig. 2.

Relative expression (arbitrary units) of ERAD (derA and hrdC) and UPR (bipA and pdiA) reporter genes in strains expressing different heterologous proteins (see Table 1 for details). Samples for Northern blot analysis were collected from these strains grown for 16 h at 30°C in liquid CM. Values were normalized for loading differences. The gene expression levels were normalized using the N402 values as reference
