Concept explainers
(a)
To explain:
The type of interactions between the side-chains of the following pairs of amino acids in the tertiary structure of a proteins “lysine and glutamate”.
Introduction:
Tertiary structure of proteins is formed by coiling, folding and twisting of the proteins to form the three-dimensional structure.
