==Overview==
==Overview==
Crystal structures of heparin-derived tetra- and hexasaccharides complexed, with basic fibroblast growth factor (bFGF) were determined at resolutions, of 1.9 and 2.2 angstroms, respectively. The heparin structure may be, approximated as a helical polymer with a disaccharide rotation of 174, degrees and a translation of 8.6 angstroms along the helix axis. Both, molecules bound similarly to a region of the bFGF surface containing, residues asparagine-28, arginine-121, lysine-126, and glutamine-135, the, hexasaccharide also interacted with an additional binding site formed by, lysine-27, asparagine-102, and lysine-136. No significant conformational, change in bFGF occurred upon heparin oligosaccharide binding, which, suggests that heparin primarily serves to juxtapose components of the FGF, signal transduction pathway.
