Each enzyme has it own unique three-dimensional structure that determines the function of the enzyme. The three-dimensional structure of enzymes is determined by the order of the amino acids in the coiled string.nzymes are large molecules with hundreds of amino acids. Only a small part of the enzyme participates in the catalysis of biochemical reactions: this is called the active site. The three-dimensional structure of the enzyme determines the appearance of the active site.
A restriction enzyme is a protein that recognizes a specific, short nucleotide sequence and cuts the DNA only at that specific site, which is known as restriction site or target sequence.More than 400 restriction enzymes have been isolated from the bacteria that manufacture them. The number of cuts in an organism's DNA made by a particular restriction enzyme is determined by the number of restriction sites specific to that enzyme in that organism's DNA. 2  A fragment of DNA produced by a pair of adjacent cuts is called a RESTRICTION FRAGMENT.
