Table 5.

Amino acid sequence divergence as a function of core, boundary or surface in tteRBP and ecRBP. Differences are classified as substitutions which are found in tteRBP relative to ecRBP.

Classification	Lose Charge	Lose Polar	Gain Charge	Gain Polar	Non-Branched to Branched	Branched to Non-Branched	V to I	I to V
Core	1	7	1	0	5	4	7	2
Boundary	4	3	4	5	6	2	3	0
Surface	6	9	18	12	0	4	0	0
