Describe the three-dimensional (tertiary) structure of an enzyme.
Answers
Answer:
Protein tertiary structure is the three dimensional shape of a protein. The tertiary structure will have a single polypeptide chain "backbone" with one or more protein secondary structures, the protein domains. Amino acid side chains may interact and bond in a number of ways.
The overall folding of the complete polypeptide chain into a precise 3D form is referred to as tertiary structure. Enzymes frequently have a tight, spherical tertiary structure. The triosephosphate isomerase (TPI) molecule's tertiary structure. Many proteins are made up of several polypeptide chains.
Enzymes are macromolecules that are made up of proteins. Except for catalytic DNA and RNA, which are classified as enzymes but not proteins. They have a well-defined amino acid sequence and range in length from 100 to 500 amino acids. They have a three-dimensional structure that is well defined.
