Percentage similarity and identity of amino acid sequences of Sec7 domains of five proteins with ARF GEP activity

	p200	Geal	ARNO	Cytol	Sec7
p200	—	44	70	70	69
Geal	30	—	54	51	54
ARNO	51	34	—	95	70
Cytol	55	36	88	—	67
Sec7	50	35	50	50	—

Percentage similarity (considering G, A, S, T, P/V, L, I, M/K, R, H/F, Y, W/D, E, N, Q as conservative differences) is above the diagonal and identity is below.
