Document Summary

Problem set questions: provide a reason explaining why the formation of secondary structure is not the main driving force for protein folding, the ridges and grooves of an helix form an angle of ~25 or ~45 to the helical axis. How do these geometric considerations constrain the packing of pairs of helices at relative angles of 50 and 20 ? (hint: see helix packing. pptx available for download on the bch 3125 bb learn site): heptad repeats define coiled coils, which are a type of supersecondary structure where two helices are wrapped around each other.
