Hierarchy of structural order in proteins(cont Quaternary structure: The packing pattern of several identical molecules that characterizes a crystalline fiber Scale: 1000 nm= 1 um Architecture: Pattern comprising several fibers of a protein that constitute a macroscopic tissue. Often contains fibers of two different proteins (collagen and elastin) and one or more proteoglycan molecules Scale: 1-10 mmHierarchy of structural order in proteins (cont.)
