*h*, θ, and Ω are calculated as described (36, 37).*h*is the distance between the centroid of the helix Cα coordinates (residues 15 to 26) and the least-squares plane fit to the Cα coordinates of the sheet (residues 3 to 12); θ is the angle of inclination of the principal moment of the helix Cα atoms with the plane of the sheet; Ω is the angle between the projection of the principal moment of the helix onto the sheet and the projection of the average least-squares fit line to the strand Cα coordinates (residues 3 to 6 and 9 to 12) onto the sheet.
