What does it mean to say protein is oligomeric?
Oligomerization of protein refers to the interaction of more than one polypeptide chains. This forms the quaternary structure, generally considered to be the highest level of organization within the protein structural hierarchy.
Why do proteins form oligomers?
In addition, oligomerization allows proteins to form large structures without increasing genome size and provides stability, while the reduced surface area of the monomer in a complex can offer protection against denaturation (1–3, 9, 13).
What is the function of globin?
Globins are small heme-proteins that reversibly bind oxygen. Their most prominent roles in vertebrates are the transport and storage of O2 for oxidative energy metabolism, but recent research has suggested alternative, non-respiratory globin functions.
Is hemoglobin an oligomer?
Consider that hemoglobin was long believed to be a homo-oligomer, made up of one kind of subunit.
Is a dimer and oligomer?
A dimer (/ˈdaɪmər/) (di-, “two” + -mer, “parts”) is an oligomer consisting of two monomers joined by bonds that can be either strong or weak, covalent or intermolecular.
What is oligomerization of proteins?
Oligomerization of protein refers to the interaction of more than one polypeptide chains. This forms the quaternary structure, generally considered to be the highest level of organization within the protein structural hierarchy.
What does oligomerize mean?
A polymer consisting of at least 2 and as many as 100 monomers. o·lig′o·mer′ic adj. o·lig′o·mer′i·za′tion n. American Heritage® Dictionary of the English… Oligomerize – definition of Oligomerize by The Free Dictionary
What is an oligomer of a protein called?
Some biologically important oligomers consist of macromolecules like proteins or nucleic acids; for instance, hemoglobin is a protein tetramer. An oligomer of amino acids is called an oligopeptide or just a peptide. An oligosaccharide is an oligomer of monosaccharides (simple sugars).
What are the advantages of oligomeric proteins?
Economy of Genetic Material. One of the principal advantages of oligomeric proteins is that large structures can be built from a limited amount of genetic material. Furthermore, it becomes easier to perform quality control since subunits containing errors can be excluded from incorporation into the final oligomer.
