PROTEINS: THREE-DIMENSIONAL STRUCTURE

A protein’s quaternary structurerefers to the spatial arrangement of its subunits. The four levels of protein structure are summarized in Fig. 6-1. Section 6-1. Secondary Structure125 Figure 6-1. Levels of protein structure. (a) Primary structure, (b) secondary structure, (c) tertiary structure, and (d) quaternary structure.
