Detailed information obtained at atomic level revealed that events taking place in the complex heated at high temperature caused important changes in the β-carotene binding site, therefore leading to a more thermodynamically stable assembly.
Star-shaped polymers, one kind of dendritic polymers with well-defined architecture and multiple polymer chains emanating from the central core, have similar topological structures to polymeric micelles and can form more stable nanoscale assemblies in selective solvents, as compared with the corresponding linear block analogues.
Thus, it appears that the addition of 69 amino acids from DISC1FP1 introduces clear differences in secondary structure compared with the control truncated DISC1 protein, resulting in the formation of larger, more stable protein assemblies.
Over and above the multiple effects of expressing amino acids 1 597, the additional 60 or 69 novel amino acids in CP60 and CP69 alter the structure of DISC1 amino acids 326 597, leading to the production of larger, more stable protein assemblies.
Whole cells expressing the protein assembly were more stable than ones with free proteins for d-HPG production, and they could be recycled six times with a conversion yield of d-HPG exceeding 90%.
Despite that the type II assembly involves large number of interactions and presumably more stable than the type I, such an assembly is seen only in one among the four structures reported here.
The fluorinated assembly is much more stable than the hydrogenated peptide dimer and the heterodimer, as judged by thermal and chemical denaturation studies and is responsible for driving the equilibrium in favor of the homodimers.
The main advantages of using high thermal mass are reduced annual energy use, reduced peak demand, a more stable internal environment, increased acoustic insulation of assemblies and improved fire ratings of assemblies.
In contrast to SaCld, both apo- and holo-LmCld form hexameric assemblies (Fig. 1), but with the interesting observation that the RZ-values of small fractions of holo-LmCld, with higher oligomeric assemblies, were larger, indicating more stable cofactor incorporation.
While most cellular protein complexes appear to contain subunits that are highly unstable when present in excess, they may also require one or more stable subunits that serve as scaffolds for complex assembly.
