Table 4. Averaged C_α distances of corresponding residues from molecular dynamics simulations^a.

	R204 - E212′ (Å)	R204′ - E212 (Å)	L205 - Y209′ (Å)	L205′ - Y209 (Å)
Wild type	8.74±0.40	8.75±0.32	6.95±0.39	6.90±0.38
R204A	8.53±0.44	8.54±0.55	6.46±0.39	5.55±0.29
R204A/Y209A	7.66±0.48	7.14±0.46	5.13±0.43	5.18±0.37

^aThe two values represent the averaged distances of C_α atoms between corresponding residues and the standard deviation of distances.
