Steps Involved in Mechanism of Protein Synthesis

The following points highlight the three main steps involved in mechanism of protein synthesis. The steps are: 1. Initiation of Protein Synthesis 2. Elongation of Polypeptide 3. Termination of Protein Synthesis. Mechanism of Protein Synthesis: Step # 1. Initiation of Protein Synthesis: (i) Amino Acid Activation: The amino acid (AA) is activated by the enzyme "aminoacylsynthetase", and energy is provided [...]

Proteins: Composition and Structure | Macromolecules

In this article we will discuss about the composition and structure of proteins. Composition of Proteins: Proteins are large molecules consisting of many amino-acids connected by "peptide linkages". Peptide bond is produced when carboxyl radical of one amino acid reacts with the amino (-NH2) group of the other amino acid. The basic structural formula of amino acids is shown in [...]

Protein: Structure and Its Synthesis | Genetics

In this article we will discuss about:- 1. Structure of Protein 2. The Role of Nucleic Acids in Protein Synthesis 3. The General Scheme and the Mechanism of Protein Synthesis. Structure of Protein: Proteins are giant molecules, formed of long chains of about hundred to several hundred amino acid molecules arranged in a variety of sequences. Although, amino acid molecules [...]
