The C-reactive protein has been given this name because it precipitates the C polysaccharide in the cell wall. Structure CRP structure Ser53, His95, Cys97, Asp112, Gly113, Gly136, Gly154, Val165, Leu166, Ile171, and Gly196 are the highly conserved residues in the primary sequence of CRP. The C-reactive protein is a homopentamer of non-covalently bound subunits. Each subunit is a 25 Da protein consisting of 224 residues bound together. The secondary structure is formed of four α-helices and three β-sheets (five-stranded, three-stranded and seven-stranded). The predominant structure is β-sheet. Residues Glu197 and Lys123 in CRP form an intermolecular ion pair. PC binding site PC stands for phosphocoline. It is a phospholipid in cell membranes and a plasma lipoproteins. Phe-66 and Glu-81 are the two key residues that enable the binding of PC. Biomedical interest CRP level is 1000 times higher in a cytokine-mediated response due to tissue injury, infection and inflammation. Therefore the CRP rate in serum is common use to detect the activity of a disease. Structural highlights This is a sample scene created with SAT to color by Group, and another to make a transparent representation of the protein. You can make your own scenes on SAT starting from scratch or loading and editing one of these sample scenes.
