title: Crystals of the cell-binding module of fibronectin obtained from a series of recombinant fragments differing in length.
abstract: A recombinant fragment corresponding to the cell adhesion module (FNIII10) of human fibronectin has been crystallized at pH 8.6 from solutions containing polyethylene glycol as precipitant. The crystals formed in the space group P2(1) with a = 30.76 A, b = 35.07 A, c = 37.66 A, beta = 106.9 degrees. There is one molecule per asymmetric unit and the crystals diffract beyond 1.75 A resolution. To improve the prospects for successful crystallization of the FNIII10 module, a series of recombinant fragments was produced with minor differences in the length of N or C-terminal segments. Only one of these variants crystallized. Interestingly, the C-terminal residue of this variant formed stable intermolecular contacts with a symmetry-related molecule in the crystal lattice.
