Stresses associated with disease may pathologically remodel the proteome by both increasing interaction strength and altering interaction partners, resulting in proteome-wide connectivity dysfunctions. Chaperones play an important role in these alterations, but how these changes are executed remains largely unknown.

Pseudomonas aeruginosa RW41 is the first bacterial strain, which could be isolated by virtue of its capability to mineralize 4-chlorobenzenesulfonic acid (4CBSA), the major polar by-product of the chemical synthesis of 1,1,1-trichloro-2,2-bis-(4-chlorophenyl)ethane (DDT). This capability makes the isolate a promising
