How does protein structure affect function

WebDec 18, 2016 · Since enzymes operate like any other protein, they too are subject to changes in the environment that can affect their function. Consider a normally functioning enzyme. It is held into a particular shape by a large number of hydrogen bonds and other interactions between amino acids and secondary motifs. WebHow do mutations cause changes in the structure and function of a protein? Mutations can lead to changes in the structure of an encoded protein or to a decrease or complete loss in its expression.Because a change in the DNA sequence affects all copies of the encoded protein, mutations can be particularly damaging to a cell or organism.
