Occurrence of protein structure elements in conserved sequence regions

BMC Structural Biology

Table 3 Statistics of secondary structure elements in conserved and random regions

Elements	Difference (random average minus conserved)	% difference from conserved	Number of prediction intervals *
Helix	419.0	7.6	3.17
Strand	-483.6	-7.1	3.51
Turn	418.7	6.7	2.92
Loop	-70.5	-0.6	0.36

* The number of prediction intervals that differentiates between conserved regions and the average of random regions. In bold lines the difference is significant with a confidence of at least 95%. Prediction interval was created by the standard deviation of the random sets multiplied by the t value for 21 degrees of freedom.
