Structures define the functions of proteins
... Each histone is organized in two domains, a characteristic ‘histone fold’ and an unstructured N-terminal ‘tail’. The histone-fold domains constrain the DNA in a central core particle and, thereby, restrict access of DNA-binding proteins. This histone tail is a flexible amino terminus of 11-37 resid ...
