What is the importance of protein structure?

The importance of the protein structure is that anything that needs to be bind is bound in the right position to give the desired effect. EXAMPLE: for lysozyme, binding to the polysaccharide substrate is very specific, each atom making contact is in precisely the right position for binding and catalysis. Lysozyme is part of the innate immune system. The specificity of reaction is determined by the precise array of charges and hydrophobic elements in the protein ie. by exact structure of each protein, this structure is determined by the sequence of AA in the polypeptide chain, which is in turn determined by the DNA bases encoding this gene.
