2. Some interesting reading about tissue transglutaminase (tTG) from Wikipedia ...

https://en.wikipedia.org/wiki/Tissue_transglutaminase#Clinical_significance

The links to celiac disease should be interpreted very carefully ... when antibodies attack tTG (destroying or inactivating it), that is what causes the tissue breakdown. It is not the tTG itself; the tTG is more likely involved in routine tissue repair, and disabling that repair mechanism leads to the disease condition. So tTG is the good guy here, and (abnormal) antibodies are the bad guys. This is what is meant by an 'autoimmune disease' -- the body's own immune system attacks essential systems the body needs for good health. However, excess tTG activity may also be associated with several other diseases, but it's not entirely clear how, or to what extent. I would certainly hope tTG is denatured in the cooking process, as most enzymes are.
