Average values of structural correlates and their correlation with $O_{\text{axis}}^2$^a

	Averages	Correlation
	CaM:eNOSp	R2
Depth of Burial (Å)	2.42 ± 1.29	0.13
Distance from Peptide (Å)	5.56 ± 3.36	0.06
Solvent Accessible Surface (Å2)	10.7 ± 16.5	0.04
Packing (Å3)	24.3 ± 16.7	0.10
Electrostatic potential (kT/e)	19.0 ± 12.7	0.14
$O_{\text{axia}}^2$	0.55 ± 0.22

^aAverage values with standard deviation for several simple structural properties for the methyl groups of CaM. Difference represents the average pair-wise difference between the two properties.

R² represents the correlation of $O_{\text{axis}}^2$ at a site with the structural property at that site.
