The tertiary structure of proteins refers ... and basic R groups that exist on the protein. The quaternary protein structure refers to the orientation and arrangement of subunits in proteins ...

Here we study how the tertiary and quaternary structure of the mitochondrial translocator protein TSPO, which binds cholesterol with nanomolar affinity, is affected by this sterol. Residue ...

and owing to the intermediacy of the dynamic structures between tertiary and quaternary structure described above, I suggest we term this level of structure of multidomain proteins 'supertertiary ...

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 ...

The structure of a protein is hierarchically arranged, from a primary to quaternary structure ... During denaturation, proteins lose their tertiary and secondary structures and become a random ...
