Transglutaminase Gluten Celiac Inflammation Autoimmunity

Image
The point of this post is that the intestines produce an enzyme, transglutaminase (TG) that normally protects the gut from toxic plant proteins, such as grain gluten, but modern food processing and antibiotics corrupt digestion of gluten to produce intestinal inflammation and a series of related autoimmune diseases including celiac, thyroiditis, diabetes, baldness and atherosclerosis.  Transglutaminase Links Proteins Enzymatically Transglutaminase is a ubiquitous enzyme produced in the intestines, thyroid, heart, skin, hair follicles, etc.  This enzyme attaches to a protein (TG + ProA ~~> TG-ProA) via amino groups extending from some of the proteins amino acids, e.g. lysine or glutamine, and then the enzyme replaces itself by another protein leaving the two proteins crosslinked (TG-ProA + ProB ~~> TG + ProA-ProB).  Another alternative reaction is to leave the original glutamine without its amino group to yield glutamic acid residues.

Celiac Gluten and Trypsin Inhibitor

---the other 200 posts---     Wheat Summary Forget the gluten.  Celiac is caused by trypsin inhibitors (ATI) that were increased in wheat fifty years ago to combat pests.  Immune response to ATI spreads to include gluten and transglutaminase that perpetuates the disease.  Celiac is an unexpected consequence of traditional plant breeding that could be fixed with GMO approaches. Plants Protect Themselves with Antibiotics, Pesticides and Trypsin Inhibitors. Plants respond to pathogens and pests by making themselves toxic.  Thus, plants produce natural antibiotics, phytoalexins, a.k.a. phytochemicals, polyphenolics or antioxidants, to kill bacteria and fungi.  They also produce chemical pesticides and proteins, e.g. trypsin inhibitor, that block the digestion and utilization of plant proteins by insects.  One of these trypsin inhibitors makes ground soybeans inedible until it is removed in water rinses during the production of tofu.  Another of t...
