Although the findings indicate that the favorable effect of proteins on the formation and stability is not due to a crowding effect, it is evident that the crowded milieu of the intracellular space is propitious for the interaction between many different proteins.
Folding within the crowded cellular milieu often requires assistance from molecular chaperones that prevent inappropriate interactions leading to aggregation and toxicity.
The presence of large amounts of macromolecules of varying shapes, sizes and compositions makes the intracellular milieu extremely crowded.
The problems related to the crowding of the intracellular milieu have been proposed to be greater for eukaryotic cells, not only for the distances an intermediate have to override to reach a given catalytic site, but especially for the presence of a number of physical obstacles, as the cytoskeleton, multi-enzymatic complexes and organelles.
Carlson ably exploits this historical milieu, describing the milling crowds in the exhibition halls; the malodorous, dangerous alleyways of the slum called Five Points; the swampy, still-wild edges of upper Manhattan.
In addition, we tested the following: cytoplasm of living Escherichia coli using in cell NMR (Serber et al., 2005); E. coli high speed lysate (Tetenbaum-Novatt et al., 2012); and buffer alone, the latter lacking crowding agents or competitors and being the milieu in which these proteins have been most studied previously (Frey et al., 2006; Lim et al., 2006; Ader et al., 2010; Yamada et al., 2010).
When the students read "The Lonely Crowd," the landmark 1950 study of their own social milieu, they didn't just discuss the book, they discussed it with its author, David Riesman.
Definitely more youthful, attracting the Hollywood 30-something crowd and those who would like to be in that milieu.
But on Sunday, the street was crowded with groups and individuals trying to understand how the milieu made the man.
After Marian died, in 1997, Clyde said, his father opened up a bit, and sometimes talked about what a tough crowd the Abstract Expressionists were, and how the anxiety of working in that milieu became almost overwhelming.
Schematics illustrate the different constructs as studied within the cellular milieu (blue circles) which vary both in total molecular weight, crowding of the FG repeats via tetramerization, and composition of FG fragments (homotypic or heterotypic).
