The method of characteristics is used with a new form of the Prandtl Meyer function at high temperature.
To test this hypothesis, a series of deletion/substitution mutants were created to disrupt the Phe4 – Trp6 – Tyr343 aromatic cluster, and each mutant protein was analyzed for its folding, stability and function at high temperature as well as in the presence of SDS and proteinase K.
We examined additional roles of ROM2 in C. neoformans and found that ROM2 plays a role in several cell functions specifically at high temperature conditions.
Reinforcement of fibrous composites by stiff particles embedded in the matrix offers the potential for simple, economical functional grading, enhanced response to mechanical loads, and improved functioning at high temperatures.
Although the Bloom cells function at high temperatures internally, the charge is maintained by chemical reactions, not combustion, so the efficiencies are much higher than at an ordinary power plant.
These conditions, however, exclude proteins that are susceptible to aggregation or loss of function at high temperatures and concentrations or require particularly high specific activity [15, 23, 25].
It is therefore important to understand how fast a protein can unfold or lose its function at high temperatures, such as near the water boiling point.
The nitrate would function at high temperatures or in an acidic condition, while the lead II) works best in a neutral aqueous solution.
In light of the foregoing arguments, it is not clear how these proteins function at high temperatures, but it is possible that they do not engage in weak binding by short motifs but undergo induced folding of extended regions resulting in much stronger binding, as observed in the assembly of translation initiation [62] or the ribosome [63].
There is considerable interest in determining what enables proteins from thermophiles to function at high temperatures, both for the practical benefit of engineering proteins for high-temperature industrial processes and as an evolutionary and biochemical puzzle.
These molecules are able to function as normal inhibitory serpins, but have developed strategies to fold and function at high temperatures (Irving et al, 2003; Fulton et al, 2005).
