Protein carbonylation is an irreversible oxidative modification that increases during organism aging and bacterial growth arrest. We analyzed whether the heat shock regulon has a role in defending Escherichia coli cells against this deleterious modification upon entry into stationary phase. Providing the cell with ectopically elevated levels of the heat(More)
The mMC5 receptor was cloned from a genomic library, mutated in the extracellular loops (EL's), expressed and tested for binding to melanocyte stimulating hormone (MSH) peptides. The EL's show low amino acid homology within the MC receptor family. Two mutants of the mMC5 receptor were created in order to investigate the participation of these regions in(More)
