TABLE 1.

The interaction matrix M_IJ, based on the shifted contact-energy matrix of Miyazawa and Jernigan (1996)

	Ala	Val	Leu	Ile	Phe	Tyr	Trp	Met
Ala	0.00	0.44	1.31	0.98	1.21	0.00	0.22	0.34
Val		1.92	2.88	2.45	2.69	1.02	1.58	1.72
Leu			3.77	3.44	3.68	2.07	2.54	2.81
Ile				2.94	3.24	1.65	2.18	2.42
Phe					3.66	2.06	2.56	2.96
Tyr						0.57	1.06	1.31
Trp							1.46	1.95
Met								1.86

The table shows absolute values (M_IJ ≤ 0).
