Nonoverlapping closed loops of around 25-35 amino acids formed via nonlocal interactions at the loop ends have been proposed as an important unit of protein structure. This hypothesis is significant as such short loops can fold quickly and so would not be bound by the Leventhal paradox, giving insight into the possible nature of the funnel in protein(More)
The closed loop hypothesis of Berezovsky and Trifonov implicates the closure of loops of length 25-35 through hydrophobic interactions at the 'locks' as a key event in protein folding. The hypothesis is supported by published analyses of nine major superfolds. Here, we have generated multiple sequence alignments for the nine superfolds with PDB codes lthb,(More)
