However, a recent study claims that membrane protein stability does not depend on the lipid composition of the membrane and arguments against lipid saturation per se Olaparib PARP inhibitor as a regulator of thermotolerance were raised. The present study supports the possibility that both lipid saturation/rigidification and point mutations that modify the protein structure at the transition state may be required for controlling the activation energy for the ratedetermining electron transfer and for inducing thermotolerance to the PSIIRC. Namely, as the growth temperature is increased to 43uC, DH{ and DS{ for the AC mutant should be Selumetinib MEK inhibitor changed for maintaining ket at 3000–3500 s21. To that end the DBI value decreases to counteract the increased fluidity of the membrane at elevated temperatures. At the same time our study suggests that in addition to the enhanced functional stabilization of the PSIIRC complex, there is a need to attenuate the impairment of the D1 repair machinery at elevated temperature, possibly by providing more CO2 as a sink for the accumulation of redox equivalents.
