Proteins that are composed of two or more subunits or polypeptides are said the have quanternary structure.
Select one:
True
False
Homework Answers
To answer this question we have to know about the basic details of the quaternary structure of proteins.
Each polypeptide chain which acts as subunits of the quaternary structure of protein are arranged in primary, secondary( alpha-helix and beta-pleated sheet) or tertiary( due to interaction between the R groups in proteins) structures. When these subunits joined and held together by hydrophobic, hydrophilic interactions or cysteine residues they form the quaternary structure of proteins. The subunits which (can be 2 or more in number) form the quaternary structure can't function of their own when separated. Some examples of quaternary structures are insulin( made up of 2 subunits), haemoglobin( made up of 4 subunits).
Therefore, the response to the answer is TRUE.

It is often said that protein complexes are made from subunits (that is,individually synthesized proteins) rather than as one long protein because it is more likely to give a correct final structure. a. Assuming an error rate of 1/10,000, what fraction of bacterial ribosomes would be constituted correctly if the proteins were synthesized from one large protein versus assembled from individual proteins? For sake of calculation assume that the ribosome is composed of 50 proteins, each 200 amino acids in...

Part 2. Adult hemoglobin is composed of two alpha subunits and two beta subunits. There are several genes that code for proteins closely related to beta globin. Each of Epsilon, Gamma, and Beta can all pair with Alpha globin to form functional hemoglobin. 1. Epsilon: expressed during early embryogenesis. 2. Gamma: expressed during later fetal development. 3. Beta: expressed after fetal development into adulthood All of the beta-family globin genes are regulated by a set of enhancer elements called the...

DNA-binding proteins are proteins that are composed of DNA-binding domains and thus have a specific or general affinity for either single or double stranded DNA. Protein X is one such protein that binds to double stranded DNA. What residues are most likely to be located in the DNA binding site of protein X and why?

1. Amino acids are considered to be either hydrophobic or hydrophilic as described by the relative polarity of their side chain. Consider a folded protein in an aqueous environment; where would the hydrophobic amino acids likely be found? -Tucked away in the middle of the folded protein -Randomly distributed throughout the protein -Exposed on the exterior surface of the folded protein 2. All proteins exhibit a primary, secondary, and tertiary structure, but not all proteins exhibit a quaternary structure. Describe...

Alcohol dehydrogenase is an enzyme composed of several polypeptide subunits. It is normally expressed at high levels in the liver and the lining of the stomach. It is essential to metabolize alcohol, as without it, drinkers would become drunk faster and stay drunk longer. A scientist is studying mutations in mice that affect the activity of the enzyme. She finds that a heterozygote having a normal allele and a mutation that deletes the gene has 50% of normal enzyme activity....
