In this article, I briefly describe how the interactions of motor proteins bring changes in cells. The activity of motor proteins The movement of organelles and macromolecules within cells mainly arises from the activity of molecular motors. Motor proteins in large aggregates gaining energy from ATP undergo cyclic conformational changes that concentrate into a unified … Read more >>
In this article, I briefly describe the two important globin proteins, hemoglobin and myoglobin, and their functions. The globin proteins The globin family of proteins having similar primary and tertiary structures is found in all classes of eukaryotes and some bacteria. The main function of globins is to store and transport oxygen. In mammals, there … Read more >>
In this article, I briefly describe the process of electrophoresis and how protein purification is related to specific activity. Separation of proteins and chromatography The cells contain thousands of varieties of proteins that can be separated based on size, charge, or binding properties. A protein can be studied in detail only when it can be … Read more >>
In this article, I briefly explain the peptides and proteins with their distinguishing properties. Proteins Proteins are the most abundant biological macromolecules present in all cells in many varieties. In a single cell, thousands of different kinds of proteins are present. Peptides and proteins are the polymers of amino acids. In every organism, the proteins … Read more >>
