Detailed explanation-1: -An enzyme’s function is intrinsically linked to its three-dimensional structure, determining how it performs substrate binding, catalysis, and regulation. X-ray crystallography has been the most important technique in the development of our understanding of enzyme structure and function.
Detailed explanation-2: -Explain how the structure of an enzyme relates to how well the function catalyzes chemical reactions. The structure of an enzyme is important because it allows for the correct substrate to enter the active site. If the enzyme is inhibited it cannot catalyze reactions because the substrate will not bind.
Detailed explanation-3: -The characteristics of an enzyme derive from the sequence of amino acids, which determine the shape of the enzyme (i.e., the structure of the active site) and hence the specificity of the enzyme.
Detailed explanation-4: -Thanks to these amino acids, an enzyme’s active site is uniquely suited to bind to a particular target-the enzyme’s substrate or substrates-and help them undergo a chemical reaction.
