In fact, each gene in cellular DNA contains the code for a unique protein structure. Not only are these proteins assembled with different amino acid sequences, but they also are held together by ...

Proteins have four levels of structure: primary (amino acid sequence), secondary (local folding patterns like alpha helices and beta sheets), tertiary (overall 3D shape), and quaternary (assembly of ...

Quaternary structure formation (assembly ... to the addition of a substoichiometric amount of fibrils to soluble NM protein to increase its rate of conversion to amyloid fibrils.
