Quizplus · Accepted Answer

Changing one amino acid may or may not affect protein function. The primary structure, or sequence of amino acids, determines the way a protein folds into its unique three-dimensional shape, which in turn determines its function. While changes in certain amino acids may have little to no effect on protein function, changes in others can completely disrupt the structure and function of the protein. Ultimately, the relationship between primary structure and protein function is complex and context-dependent.
