TGase activities of the pastes with NFB and MFB decreased
significantly after setting (p < 0.05) (Fig. 2) as the result of crosslinking
by TGase. Endogenous TGase contains 38 glutaminyl and
42 lysyl residues, which allows autocatalytical cross-linking
(homoaggregates) when calcium ions are present (Wilhelm,
Meinhardt, & Seitz, 1996).
