|Description:||This is the sequel to puzzle 675, where you folded two symmetric chains attached to a central catalyst molecule. We've kept the catalyst and the chains identical, but we're moving beyond just folding: it's time to make this catalyst go turbo. It needs protons fed to its inner nitrogen (an H-bond acceptor) to go faster, so we're giving you a large bonus for making an H-bond to this atom. Fair warning: it's a bit crowded in there, so the angle has to be just-right to avoid a clash. This is the atom in the central, bent ring that attaches to the flat outer ring. It looks blue in CPK mode and glows red when "show bondable atoms" and "show bonds (non-protein)" are turned on, under "View". Try to come up with stable folds that reach this atom!|
