Co-expression analysis, proteomic and metabolomic study on the impact of a Deg/HtrA protease triple mutant in Synechocystis sp. PCC 6803 exposed to temperature and high light stress.

Abstract excerpt

Members of the DegP/HtrA protease family are widespread in nature and play an important role in proteolysis of misfolded and damaged proteins. The cyanobacterium Synechocystis sp. PCC 6803 contains three Deg proteases, HhoA (Sll1679), HhoB (Sll1427) and HtrA (Slr1204). Using the proteomic or metabolomic approach we investigated a triple deletion mutant (Δdeg) exposed to light or temperature stress. To cope with...
