Structural Implications :

Glu76 is an exposed residue. (the surface accessibility from the modelled FIXa structure is 5).

Glu76 is in a alpha helix region of the FIXa structure (the DSSP assignment from the modelled FIXa domains is H).

The substitution involves a Gamma carboxy glutamic acid(CGU) residue in the Gla domain.
