abstract = {Despite its biological importance, the interaction between
fibronectin (FN) and collagen, two abundant and crucial
tissue components, has not been well characterized on a
structural level. Here, we analyzed the four interactions
formed between epitopes of collagen type I and the
collagen-binding fragment (gelatin-binding domain (GBD)) of
human FN using solution NMR, fluorescence, and small angle
x-ray scattering methods. Collagen association with FN
modules (8-9)FnI occurs through a conserved structural
mechanism but exhibits a 400-fold disparity in affinity
between collagen sites. This disparity is reduced in the
full-length GBD, as (6)FnI(1-2)FnII(7)FnI binds a specific
collagen epitope next to the weakest (8-9)FnI-binding site.
The cooperative engagement of all GBD modules with collagen
results in four broadly equipotent FN-collagen interaction
sites. Collagen association stabilizes a distinct monomeric
GBD conformation in solution, giving further evidence to the
view that FN fragments form well defined functional and
structural units.},
