PREDITOR is a program for
cting φ, ψ, χ
, and ω
sion angles in proteins from
H chemical shifts and sequential homology. PREDITOR's accuracy in predicting φ and ψ is close to 90%. The average χ
accuracy is 84% while the ω accuracy is 99.98% for trans peptide bond identification and 93% for cis peptide bond identification. Overall, the program is 35X faster and its predictions are approximately 20% better than existing methods. You can find additional information about PREDITOR protocol on...
