No. It is possible for an enzyme to have a quaternary structure, but it strictly depends on the enzyme. For example, β-galactosidase, more commonly known as lactase, is the enzyme that breaks the β linkage between the disaccharide lactose into its componenets glucose and galactose. β-galactosidase is a tetramer, meaning it has four subunits. This is an example of an enzyme with a quaternary structure. Enzymes can also be tertiary structures, meaning only one subunit. The quaternary structure is just made up of more than one tertiary structures. Depending on the enzyme, it can either function with only one amino acid chain coiled into a conformation (tertiary) or a group of amino acid chains coiled into a conformation (quaternary).

Proteins with more than one polypeptide chain have what structure?
These have quaternary structure. This is the overall shape of all the chains combined. The 3D shape of one polypeptide chain is the tertiary structure.
Is collagen a secondary or tertiary structure?
With most proteins, it has a secondary and tertiary structure.
Interaction between individual polypeptide chains to form a protein complex is a what kind of structure?
I'm pretty sure it's quaternary"If several protein chains associate w/ one another to form a functional protein, the protein is said to have a quaternary structure" - 'Human Physiology, 4th E', Dee Unglaub Silverthorn
What aspect of protein structure are stabilized or assisted by hydrogen bonds?
secondary, tertiary, and quaternary structures, but not primary structure
Which level of protein structure may be stabilized by covalent bonds?
Primary, tertiary and quaternary levels of protein structure.
A fully functional molecule of hemoglobin is what kind of protein structure?
The structure of the hemoglobin in a molecule is the quaternary structure.
Proteins with more than one polypeptide chain have what structure?
These have quaternary structure. This is the overall shape of all the chains combined. The 3D shape of one polypeptide chain is the tertiary structure.
Differentiate the four types of protein structure?
There are four types of protein structure. These include primary structure, secondary structure, tertiary structure, and quaternary structure. Primary structure is the amino acid sequence. Secondary structure is the shape of the molecule. Tertiary structure is the interaction between groups. Quaternary structure is the interactions between protein subunits.
What type of structure do proteins which act as enzymes possess?
quaternary structure
Quaternary structure of proteins?
The quaternary structure is the overall structure of an enzyme complex. This is made of at least two separate polypeptide chains. The 3D structure of one polypeptide is known as the tertiary structure.
What are the four levels of protein structure?
primary, secondary, tertiary, and quaternary
Hemoglobin represents which level of protein organization?
Haemoglobin has a protein structure upto quarternary structure since it is a dimer made up of two monomeric units, each of which are two in number. Thus the overall structure has 4 monomeric units.
Is hemoglobin a protein that exhibits the quaternary structure of protein folding?
The tertiary structure is the folding
The association of four subunit peptides in a fully functional molecule of hemoglobin is a good example of?
The quaternary structure of proteins.
Which level of protein structure has four subunit peptides?
Quaternary
Is collagen a secondary or tertiary structure?
With most proteins, it has a secondary and tertiary structure.
What level of structure in proteins is held together by intermolecular R group interactions?
quaternary structure
