General Information

General Information	Comment	Organism
physiological function	upon high light exposure, the FtsH1 and FtsH2 and subunits display a shorter half-life, which is counterbalanced by an increase in FTSH1/2 mRNA levels, resulting in modest upregulation of FtsH1/2 proteins. High light increases the protease activity through a redox-controlled reduction of intermolecular disulfide bridges. In a FTSH1 promoter-deficient mutant, the abundance of FtsH1 and FtsH2 proteins are loosely coupled (decreased by 70% and 30%, respectively) with no formation of large and stable homo-oligomers. High light tolerance is tightly correlated with the abundance of the FtsH protease	Chlamydomonas reinhardtii
