Quaternary structure of proteins consists of multiple polypeptide subunits coming together to form a functional protein complex. If a protein has four subunit peptides, it exhibits quaternary structure.
Protein kinase A is activated by the second messenger through a process called phosphorylation. When the second messenger binds to the regulatory subunit of protein kinase A, it causes a conformational change that releases the catalytic subunit. This released catalytic subunit is then able to phosphorylate target proteins, leading to various cellular responses.
A ribosome is composed of two subunits, a large subunit and a small subunit, made up of a combination of ribosomal RNA (rRNA) and protein molecules. The large subunit is responsible for peptide bond formation during protein synthesis, while the small subunit helps in mRNA recognition and initiation of protein synthesis.
Streptomycin binds to bacterial 30S ribosomal subunit and inhibits protein production by the bacteria. Human beings are are not affected because our ribosomes have a 40S subunit and a 60S subunit, no 30S subunit.
No, the B-subunit of hemoglobin A is a protein subunit, not a DNA molecule. Hemoglobin is composed of four protein subunits (two alpha and two beta) that come together to form the hemoglobin molecule, which carries oxygen in red blood cells. The instructions for making these protein subunits are found in the DNA of our cells.
The acid subunit of a protein polymer is an amino acid. Amino acids are the building blocks of proteins and consist of an amino group, a carboxyl group, and a side chain. The sequence of amino acids in a protein determines its structure and function.
