abstract = {Protein structures often feature beta-sheets in which
adjacent beta-strands have large sequence separation. How
the folding process orchestrates the formation and correct
arrangement of these strands is not comprehensively
understood. Particularly challenging are proteins in which
beta-strands at the N and C termini are neighbors in a
beta-sheet. The N-terminal beta-strand is synthesized early
on, but it can not bind to the C terminus before the chain
is fully synthesized. During this time, there is a danger
that the beta-strand at the N terminus interacts with nearby
molecules, leading to potentially harmful aggregates of
incompletely folded proteins. Simulations of the C-terminal
fragment of Top7 show that this risk of misfolding and
aggregation can be avoided by a "caching" mechanism that
relies on the "chameleon" behavior of certain segments.},
