High-resolution structural studies of the factor XIIIa crosslinking site and the first type 1 module of fibronectin.
Potts J.R., Phan I., Williams M.J., Campbell I.D.
The N-terminal domain of fibronectin undergoes factor XIIIa-catalysed crosslinking to fibrin, bacteria and collagen. The reactive glutamine residue is in an extended, random coil 'tail' of about 18 residues that would be accessible for crosslinking.
