Interface composition of cross-β PSAMs

	Surface Area Buried (Å2) *	Nonpolar Contacts
YY/LF †	1323	66%
YY/LF (SLB) ‡	894	71%
FL/LF †	1264	68%
FL/LF (SLB) ‡	712	77%

^*Surface area burial is reported for a single subunit, and is derived from the average value of the two subunits comprising each cross-β PSAM.

^†Buried surface area for the entire PSAM.

^‡Buried surface area only for the single-layer β-sheet segment (residues 118–209).
