et al., 2004; Du et al., 2007). Transglutaminase has been shown to graft
protein polypeptides, or fluorescein cadaverine onto the wool fibre surface
for special effects. It is reported that the crosslinking within wool fibres by
transglutaminase can improve the resistance to enzymatic cleavage, and
increase the resistance of wool to chemical and mechanical disruption. This
was claimed to be beneficial for protecting wool garments from detergent
damage (Cortez et al., 2005, 2007). However, the amount of lysine and
glutamine residues available may be limited, especially on the surface of
wool fibre, restricting the extent of enzyme reaction. Therefore this may
affect the wide application of transglutaminases on wool.
