Recognition accuracy for specific interactions between TFs and native bound DNA sequences

Accuracy Top 1(%) Top 10(%) Top 20(%) Top 1(%) Top 5(%)
Whole structural set 39.7 70.2 77.3 79.4 90.1
α-Helixa 26.3 54.4 63.2 66.7 82.5
α-Helix + β-stranda 49.4 79.2 85.7 87.0 94.8

aα-helix and β-strand refer to the secondary structures of DNA-binding sites. There are 57 proteins that bind DNA with α-helix only, 77 proteins bind to DNA with both α-helix and β-strand structures.
