Helix packing angle preferences

J U Bowie. Nat Struct Biol. 1997 Nov.

Abstract

The distribution of interaxial angles between packed alpha-helices has been explained by a number of elegant models describing how side chains on helices can interdigitate without steric conflicts. Here I show that much of the apparent preference for particular angles is due to statistical bias and that true packing angle preferences are not well described by regular packing models.
