The structure of proteins can be altered by three types of mutations: 1. Point Mutations: Point mutations involve addition, deletion or replacement of base pair in a gene. 2. Chromosomal Mutations: Addition or deletion of DNA cause mutations during crossing over. 3. Jumping genes also cause change in protein structure by shuffling their location from one chromosome to another. The [...]
The following points highlight the top two bonds relating to protein structure. The bonds are: 1. Strong Bonds 2. Weak Bonds. Protein Structure: Bond # 1. Strong Bonds: A. Peptide bonds: The primary structure of proteins is derived from peptide bonds which can be established by the following evidences: i. Proteases produce polypeptides by hydrolyzing proteins. They can also hydrolyze [...]
The following points highlight the four structure types of proteins. The types are: 1. Primary Structure 2. Secondary Structure 3. Tertiary Structure 4. Quaternary Structure. Type # 1. Primary Structure: Peptide bond is formed by the amino acids linked by carboxyl group of one amino acid with the α-amino group of another amino acid as shown: H2N-CH2-CO-NH-CH2-COOH Glycyl-Glycine Thus, they [...]
