Top 5 Protein inside of the body
INTRODUCTION
All the cells of your body contain protein, and this protein is continually broken down and remodeled to meet your growth and maintenance needs. Consuming sufficient protein in your daily diet ensures you have adequate raw materials to replenish these proteins. Protein digestion, in which your body breaks down dietary protein into usable amino acids, makes this nutrient available to your cells in support of muscle maintenance, immune function, hormone synthesis, red blood cell formation and tissue repair.1. DNA polymerase - DNA polymerase is a protein (enzyme) that binds and copies DNA. It creates two new DNA molecules, each containing one new and old strand. This DNA is then separated and divided into two new cells during mitosis.
Proteasome - Proteasomes are large protein complexes within cells that degrade proteins. Almost like a garbage disposal, proteins are threaded into them. They cleave these into small peptides, following with aminopeptidases in the cytosol further degrade them into amino acids.
Hemoglobin - Hemoglobin is a protein found within red blood cells that is coupled to iron. It enables red blood cells to bind and transport oxygen. Binding of oxygen causes conformational changes in hemoglobin that allow it to hold onto the molecule, and then release it at the right time.
Lectins - Lectins are sugar-binding proteins that function in protein synthesis. They bind to proteins in the endoplasmic reticulum and ensure they are properly folded.
Kinases - Kinases are proteins in the cell that phosphorylate (add a phosphate) other proteins. This can either activate or deactivate a protein. Their analog, phosphatases, remove phosphates.
