Modular portions of a protein that fold into stable conformations with specific functional capabilities are referred to as_________ .

Question

Quizplus · Accepted Answer

The definition provided matches that of a protein domain, which are structurally and functionally independent units within a larger protein. Protein subunits refer to individual protein molecules that come together to form a larger protein complex, while protein quaternary structures relate to the arrangement of multiple protein subunits within a single macromolecule. Protein chaperones assist in protein folding and do not generally refer to the folded stability of specific domains. Protein secondary structures describe local folding patterns of the protein backbone, rather than discrete functional units.
